-	  ISDN support in the linux kernel is moving towards a new API,

- * Notes:
- * Version 0.99 is the first release of this driver and there are
- * certainly a few bugs.
- *
- * Please don't report any malfunction to me without sending
- * (compressed) debug-logs.
- * It would be nearly impossible to retrace it.
- *
- * Log D-channel-processing as follows:
- *
- * 1. Load hisax with card-specific parameters, this example ist for
- *    Formula-n enter:now ISDN PCI and compatible
- *    (f.e. Gerdes Power ISDN PCI)
- *
- *    modprobe hisax type=41 protocol=2 id=gerdes
- *
- *    if you chose an other value for id, you need to modify the
- *    code below, too.
- *
- * 2. set debug-level
- *
- *    hisaxctrl gerdes 1 0x3ff
- *    hisaxctrl gerdes 11 0x4f
- *    cat /dev/isdnctrl >> ~/log &
- *
- * Please take also a look into /var/log/messages if there is
- * anything importand concerning HISAX.
- *
- *
- * Credits:
- * Programming the driver for Formula-n enter:now ISDN PCI and
- * necessary this driver for the used Amd 7930 D-channel-controller
- * was spnsored by Formula-n Europe AG.
- * Thanks to Karsten Keil and Petr Novak, who gave me support in
- * Hisax-specific questions.
- * I want so say special thanks to Carl-Friedrich Braun, who had to
- * answer a lot of questions about generally ISDN and about handling
- * of the Amd-Chip.

- * Notes:
- * This driver interfaces to netjet.c which performs B-channel
- * processing.
- *
- * Version 0.99 is the first release of this driver and there are
- * certainly a few bugs.
- * It isn't testet on linux 2.4 yet, so consider this code to be
- * beta.
- *
- * Please don't report me any malfunction without sending
- * (compressed) debug-logs.
- * It would be nearly impossible to retrace it.
- *
- * Log D-channel-processing as follows:
- *
- * 1. Load hisax with card-specific parameters, this example ist for
- *    Formula-n enter:now ISDN PCI and compatible
- *    (f.e. Gerdes Power ISDN PCI)
- *
- *    modprobe hisax type=41 protocol=2 id=gerdes
- *
- *    if you chose an other value for id, you need to modify the
- *    code below, too.
- *
- * 2. set debug-level
- *
- *    hisaxctrl gerdes 1 0x3ff
- *    hisaxctrl gerdes 11 0x4f
- *    cat /dev/isdnctrl >> ~/log &
- *
- * Please take also a look into /var/log/messages if there is
- * anything importand concerning HISAX.
- *
- *
- * Credits:
- * Programming the driver for Formula-n enter:now ISDN PCI and
- * necessary the driver for the used Amd 7930 D-channel-controller
- * was spnsored by Formula-n Europe AG.
- * Thanks to Karsten Keil and Petr Novak, who gave me support in
- * Hisax-specific questions.
- * I want so say special thanks to Carl-Friedrich Braun, who had to
- * answer a lot of questions about generally ISDN and about handling
- * of the Amd-Chip.

-config ISDN_PPP
-	bool "Support synchronous PPP"
-	depends on INET
-	select SLHC
-	help
-	  Over digital connections such as ISDN, there is no need to
-	  synchronize sender and recipient's clocks with start and stop bits
-	  as is done over analog telephone lines. Instead, one can use
-	  "synchronous PPP". Saying Y here will include this protocol. This
-	  protocol is used by Cisco and Sun for example. So you want to say Y
-	  here if the other end of your ISDN connection supports it. You will
-	  need a special version of pppd (called ipppd) for using this
-	  feature. See <file:Documentation/isdn/README.syncppp> and
-	  <file:Documentation/isdn/syncPPP.FAQ> for more information.
-
-config ISDN_PPP_VJ
-	bool "Use VJ-compression with synchronous PPP"
-	depends on ISDN_PPP
-	help
-	  This enables Van Jacobson header compression for synchronous PPP.
-	  Say Y if the other end of the connection supports it.
-
-config ISDN_MPP
-	bool "Support generic MP (RFC 1717)"
-	depends on ISDN_PPP
-	help
-	  With synchronous PPP enabled, it is possible to increase throughput
-	  by bundling several ISDN-connections, using this protocol. See
-	  <file:Documentation/isdn/README.syncppp> for more information.
-
-config IPPP_FILTER
-	bool "Filtering for synchronous PPP"
-	depends on ISDN_PPP
-	help
-	  Say Y here if you want to be able to filter the packets passing over
-	  IPPP interfaces.  This allows you to control which packets count as
-	  activity (i.e. which packets will reset the idle timer or bring up
-	  a demand-dialled link) and which packets are to be dropped entirely.
-	  You need to say Y here if you wish to use the pass-filter and
-	  active-filter options to ipppd.
-
-config ISDN_PPP_BSDCOMP
-	tristate "Support BSD compression"
-	depends on ISDN_PPP
-	help
-	  Support for the BSD-Compress compression method for PPP, which uses
-	  the LZW compression method to compress each PPP packet before it is
-	  sent over the wire. The machine at the other end of the PPP link
-	  (usually your ISP) has to support the BSD-Compress compression
-	  method as well for this to be useful. Even if they don't support it,
-	  it is safe to say Y here.
-
-config ISDN_AUDIO
-	bool "Support audio via ISDN"
-	help
-	  If you say Y here, the modem-emulator will support a subset of the
-	  EIA Class 8 Voice commands. Using a getty with voice-support
-	  (mgetty+sendfax by <gert@greenie.muc.de> with an extension, available
-	  with the ISDN utility package for example), you will be able to use
-	  your Linux box as an ISDN-answering machine. Of course, this must be
-	  supported by the lowlevel driver also. Currently, the HiSax driver
-	  is the only voice-supporting driver. See
-	  <file:Documentation/isdn/README.audio> for more information.
-
-config ISDN_TTY_FAX
-	bool "Support AT-Fax Class 1 and 2 commands"
-	depends on ISDN_AUDIO
-	help
-	  If you say Y here, the modem-emulator will support a subset of the
-	  Fax Class 1 and 2 commands. Using a getty with fax-support
-	  (mgetty+sendfax, hylafax), you will be able to use your Linux box as
-	  an ISDN-fax-machine. This must be supported by the lowlevel driver
-	  also. See <file:Documentation/isdn/README.fax> for more information.
-
-config ISDN_X25
-	bool "X.25 PLP on top of ISDN"
-	depends on X25
-	help
-	  This feature provides the X.25 protocol over ISDN connections.
-	  See <file:Documentation/isdn/README.x25> for more information
-	  if you are thinking about using this.
-
-
-menu "ISDN feature submodules"
-
-config ISDN_DRV_LOOP
-	tristate "isdnloop support"
-	depends on BROKEN_ON_SMP
-	help
-	  This driver provides a virtual ISDN card. Its primary purpose is
-	  testing of linklevel features or configuration without getting
-	  charged by your service-provider for lots of phone calls.
-	  You need will need the loopctrl utility from the latest isdn4k-utils
-	  package to set up this driver.
-
-config ISDN_DIVERSION
-	tristate "Support isdn diversion services"
-	help
-	  This option allows you to use some supplementary diversion
-	  services in conjunction with the HiSax driver on an EURO/DSS1
-	  line.
-
-	  Supported options are CD (call deflection), CFU (Call forward
-	  unconditional), CFB (Call forward when busy) and CFNR (call forward
-	  not reachable). Additionally the actual CFU, CFB and CFNR state may
-	  be interrogated.
-
-	  The use of CFU, CFB, CFNR and interrogation may be limited to some
-	  countries. The keypad protocol is still not implemented. CD should
-	  work in all countries if the service has been subscribed to.
-
-	  Please read the file <file:Documentation/isdn/README.diversion>.

-   the framework and the (de)compressor. Bad enough, LZS is different
-   (and any other compressor may be different, too). It has multiple
-   histories (eventually) and needs to Reset each of them independently
-   and thus uses multiple outstanding Acks and history numbers as an
-   additional parameter to Reqs/Acks.
-   All that makes it harder to port the reset state engine into the
-   kernel because it is not just the same simple one as in (i)pppd but
-   it must be able to pass additional parameters and have multiple out-
-   standing Acks. We are trying to achieve the impossible by handling
-   reset transactions independent by their id. The id MUST change when
-   the data portion changes, thus any (de)compressor who uses more than
-   one resettable state must provide and recognize individual ids for
-   each individual reset transaction. The framework itself does _only_
-   differentiate them by id, because it has no other semantics like the
-   (de)compressor might.
-   This looks like a major redesign of the interface would be nice,
-   but I don't have an idea how to do it better. */

+/* In the dynamic configuration interface, the switch exposes a register-like
+ * view of some of the static configuration tables.
+ * Many times the field organization of the dynamic tables is abbreviated (not
+ * all fields are dynamically reconfigurable) and different from the static
+ * ones, but the key reason for having it is that we can spare a switch reset
+ * for settings that can be changed dynamically.
+ *
+ * This file creates a per-switch-family abstraction called
+ * struct sja1105_dynamic_table_ops and two operations that work with it:
+ * - sja1105_dynamic_config_write
+ * - sja1105_dynamic_config_read
+ *
+ * Compared to the struct sja1105_table_ops from sja1105_static_config.c,
+ * the dynamic accessors work with a compound buffer:
+ *
+ * packed_buf
+ *
+ * |
+ * V
+ * +-----------------------------------------+------------------+
+ * |              ENTRY BUFFER               |  COMMAND BUFFER  |
+ * +-----------------------------------------+------------------+
+ *
+ * <----------------------- packed_size ------------------------>
+ *
+ * The ENTRY BUFFER may or may not have the same layout, or size, as its static
+ * configuration table entry counterpart. When it does, the same packing
+ * function is reused (bar exceptional cases - see
+ * sja1105pqrs_dyn_l2_lookup_entry_packing).
+ *
+ * The reason for the COMMAND BUFFER being at the end is to be able to send
+ * a dynamic write command through a single SPI burst. By the time the switch
+ * reacts to the command, the ENTRY BUFFER is already populated with the data
+ * sent by the core.
+ *
+ * The COMMAND BUFFER is always SJA1105_SIZE_DYN_CMD bytes (one 32-bit word) in
+ * size.
+ *
+ * Sometimes the ENTRY BUFFER does not really exist (when the number of fields
+ * that can be reconfigured is small), then the switch repurposes some of the
+ * unused 32 bits of the COMMAND BUFFER to hold ENTRY data.
+ *
+ * The key members of struct sja1105_dynamic_table_ops are:
+ * - .entry_packing: A function that deals with packing an ENTRY structure
+ *		     into an SPI buffer, or retrieving an ENTRY structure
+ *		     from one.
+ *		     The @packed_buf pointer it's given does always point to
+ *		     the ENTRY portion of the buffer.
+ * - .cmd_packing: A function that deals with packing/unpacking the COMMAND
+ *		   structure to/from the SPI buffer.
+ *		   It is given the same @packed_buf pointer as .entry_packing,
+ *		   so most of the time, the @packed_buf points *behind* the
+ *		   COMMAND offset inside the buffer.
+ *		   To access the COMMAND portion of the buffer, the function
+ *		   knows its correct offset.
+ *		   Giving both functions the same pointer is handy because in
+ *		   extreme cases (see sja1105pqrs_dyn_l2_lookup_entry_packing)
+ *		   the .entry_packing is able to jump to the COMMAND portion,
+ *		   or vice-versa (sja1105pqrs_l2_lookup_cmd_packing).
+ * - .access: A bitmap of:
+ *	OP_READ: Set if the hardware manual marks the ENTRY portion of the
+ *		 dynamic configuration table buffer as R (readable) after
+ *		 an SPI read command (the switch will populate the buffer).
+ *	OP_WRITE: Set if the manual marks the ENTRY portion of the dynamic
+ *		  table buffer as W (writable) after an SPI write command
+ *		  (the switch will read the fields provided in the buffer).
+ *	OP_DEL: Set if the manual says the VALIDENT bit is supported in the
+ *		COMMAND portion of this dynamic config buffer (i.e. the
+ *		specified entry can be invalidated through a SPI write
+ *		command).
+ *	OP_SEARCH: Set if the manual says that the index of an entry can
+ *		   be retrieved in the COMMAND portion of the buffer based
+ *		   on its ENTRY portion, as a result of a SPI write command.
+ *		   Only the TCAM-based FDB table on SJA1105 P/Q/R/S supports
+ *		   this.
+ * - .max_entry_count: The number of entries, counting from zero, that can be
+ *		       reconfigured through the dynamic interface. If a static
+ *		       table can be reconfigured at all dynamically, this
+ *		       number always matches the maximum number of supported
+ *		       static entries.
+ * - .packed_size: The length in bytes of the compound ENTRY + COMMAND BUFFER.
+ *		   Note that sometimes the compound buffer may contain holes in
+ *		   it (see sja1105_vlan_lookup_cmd_packing). The @packed_buf is
+ *		   contiguous however, so @packed_size includes any unused
+ *		   bytes.
+ * - .addr: The base SPI address at which the buffer must be written to the
+ *	    switch's memory. When looking at the hardware manual, this must
+ *	    always match the lowest documented address for the ENTRY, and not
+ *	    that of the COMMAND, since the other 32-bit words will follow along
+ *	    at the correct addresses.

+/* The switch is so retarded that it makes our command/entry abstraction
+ * crumble apart.
+ *
+ * On P/Q/R/S, the switch tries to say whether a FDB entry
+ * is statically programmed or dynamically learned via a flag called LOCKEDS.
+ * The hardware manual says about this fiels:
+ *
+ *   On write will specify the format of ENTRY.
+ *   On read the flag will be found cleared at times the VALID flag is found
+ *   set.  The flag will also be found cleared in response to a read having the
+ *   MGMTROUTE flag set.  In response to a read with the MGMTROUTE flag
+ *   cleared, the flag be set if the most recent access operated on an entry
+ *   that was either loaded by configuration or through dynamic reconfiguration
+ *   (as opposed to automatically learned entries).
+ *
+ * The trouble with this flag is that it's part of the *command* to access the
+ * dynamic interface, and not part of the *entry* retrieved from it.
+ * Otherwise said, for a sja1105_dynamic_config_read, LOCKEDS is supposed to be
+ * an output from the switch into the command buffer, and for a
+ * sja1105_dynamic_config_write, the switch treats LOCKEDS as an input
+ * (hence we can write either static, or automatically learned entries, from
+ * the core).
+ * But the manual contradicts itself in the last phrase where it says that on
+ * read, LOCKEDS will be set to 1 for all FDB entries written through the
+ * dynamic interface (therefore, the value of LOCKEDS from the
+ * sja1105_dynamic_config_write is not really used for anything, it'll store a
+ * 1 anyway).
+ * This means you can't really write a FDB entry with LOCKEDS=0 (automatically
+ * learned) into the switch, which kind of makes sense.
+ * As for reading through the dynamic interface, it doesn't make too much sense
+ * to put LOCKEDS into the command, since the switch will inevitably have to
+ * ignore it (otherwise a command would be like "read the FDB entry 123, but
+ * only if it's dynamically learned" <- well how am I supposed to know?) and
+ * just use it as an output buffer for its findings. But guess what... that's
+ * what the entry buffer is for!
+ * Unfortunately, what really breaks this abstraction is the fact that it
+ * wasn't designed having the fact in mind that the switch can output
+ * entry-related data as writeback through the command buffer.
+ * However, whether a FDB entry is statically or dynamically learned *is* part
+ * of the entry and not the command data, no matter what the switch thinks.
+ * In order to do that, we'll need to wrap around the
+ * sja1105pqrs_l2_lookup_entry_packing from sja1105_static_config.c, and take
+ * a peek outside of the caller-supplied @buf (the entry buffer), to reach the
+ * command buffer.

+TODO: Remove in late 2019 unless there are users
+
+
+I tried to find any indication of whether the capi drivers are
+still in use, and have not found anything  from a long time ago.
+
+With public ISDN networks almost completely shut down over the past 12
+months, there is very little you can actually do with this hardware. The
+main remaining use case would be to connect ISDN voice phones to an
+in-house installation with Asterisk or LCR, but anyone trying this in
+turn seems to be using either the mISDN driver stack, or out-of-tree
+drivers from the hardware vendors.
+
+I may of course have missed something, so I would suggest moving
+these into drivers/staging/ just in case someone still uses one
+of the three remaining in-kernel drivers (avm, hysdn, gigaset).
+
+If nobody complains, we can remove them entirely in six months,
+or otherwise move the core code and any drivers that are still
+needed back into drivers/isdn.
+
+  Arnd Bergmann <arnd@arndb.de>
