Since f658b90977d2 ("r8169: fix DMA being used after buffer free if WoL is

rtl_wol_shutdown_quirk(). And since 120068481405 ("r8169: fix failing WoL")
CmdRxEnb is still enabled when we get here. So we can remove the function.

If it finds no completed transactions, gsi_channel_trans_complete()
calls gsi_channel_update() to check hardware. If new transactions
have completed, gsi_channel_update() records that, then calls
gsi_channel_trans_complete() to return the first of those found.
This recursion won't go any further, but can be avoided if we
have gsi_channel_update() only be responsible for updating state
after accessing hardware.
Change gsi_channel_update() so it simply checks for and handles
new completions, without returning a value. If it needs to call
that function, have gsi_channel_trans_complete() determine whether
there are new transactions available after the update.

None of the transaction lists are actually needed any more, because
transaction IDs (which have been shown to be equivalent) are used
instead. So we can remove all of them, as well as the spinlock
that protects updates to them.
Not requiring a lock simplifies gsi_trans_free() as well; we only
need to check the reference count once to decide whether we've hit
the last reference.
This makes the links field in the gsi_trans structure unused, so get
rid of that as well.

The only place the trans_info->alloc list is used is when
initializing it, when adding a transaction to it when allocation
finishes, and when moving a transaction from that list to the
committed list.
We can just skip putting a transaction on the allocated list, and
add it (rather than move it) to the committed list when it is
committed.
On additional caveat is that an allocated transaction that's
committed without any TREs added will be immediately freed. Because
we aren't adding allocated transactions to a list any more, the
list links need to be initialized to ensure they're valid at the
time list_del() is called for the transaction.
Then we can safely eliminate the allocated transaction list.

In gsi_channel_trans_complete(), use the completed and pending IDs
to determine whether there are any transactions in completed state.
Similarly, in gsi_channel_trans_cancel_pending(), use the pending
and committed IDs to mark pending transactions cancelled. Rearrange
the logic a bit there for a simpler result.
This removes the only user of list_last_entry_or_null(), so get rid
of that macro.

All switch families supported by the ocelot lib (ocelot, felix, seville)
export the same registers so far. But for example felix also has TSN
counters, while the others don't.
To reduce the bloat even further, create an OCELOT_COMMON_STATS() macro
which just lists all stats that are common between switches. The array
elements are still replicated among all of vsc9959_stats_layout,
vsc9953_stats_layout and ocelot_stats_layout.

The current definition of struct ocelot_stat_layout is long-winded (4
lines per entry, and we have hundreds of entries), so we could make an
effort to use the C preprocessor and reduce the line count.
Create an implicit correspondence between enum ocelot_reg, which tells
us the register address (SYS_COUNT_RX_OCTETS etc) and enum ocelot_stat
which allows us to index the ocelot->stats array (OCELOT_STAT_RX_OCTETS
etc), and don't require us to specify both when we define what stats
each switch family has.
Create an OCELOT_STAT() macro that pairs only an enum ocelot_stat to an
enum ocelot_reg, and an OCELOT_STAT_ETHTOOL() macro which also contains
a name exported to the unstructured ethtool -S stringset API. For now,
we define all counters as having the OCELOT_STAT_ETHTOOL() kind, but we
will add more counters in the future which are not exported to the
unstructured ethtool -S.

present in DSA
DSA is integrated with the new standardized ethtool -S --groups option,
but the felix driver only exports unstructured statistics.
Reuse the array of 64-bit statistics collected by ocelot_check_stats_work(),
but just export select values from it.
Since ocelot_check_stats_work() runs periodically to avoid 32-bit
overflow, and the ethtool calling context is sleepable, we update the
64-bit stats one more time, to provide up-to-date values. The locking
scheme with a mutex followed by a spinlock is a bit hard to digest, so
we create and use a ocelot_port_stats_run() helper with a callback that
populates the ethool stats group the caller is interested in.
The exported stats are:
ethtool -S swp0 --groups eth-phy
ethtool -S swp0 --groups eth-mac
ethtool -S swp0 --groups eth-ctrl
ethtool -S swp0 --groups rmon
ethtool --include-statistics --show-pause swp0

We want to introduce elements kept in ocelot->stats that aren't exposed
to the unstructured ethtool -S (so they won't have their name populated),
but are otherwise checked for 32-bit wraparounds by
ocelot_port_update_stats().
This isn't possible today because ocelot_prepare_stats_regions() skips
over ocelot_stat_layout elements with no name. Now that we've changed
struct ocelot_stat_layout to keep the absolute register address rather
than the offset relative to SYS_CNT, we can make use of the unpopulated
"reg" value of 0 to mean that the counter isn't present on the current
switch revision, and skip it from the preparation of bulk regions.

if_link.h says:
* @rx_dropped: Number of packets received but not processed,
* e.g. due to lack of resources or unsupported protocol.
* For hardware interfaces this counter may include packets discarded
* due to L2 address filtering but should not include packets dropped
* by the device due to buffer exhaustion which are counted separately in
* @rx_missed_errors (since procfs folds those two counters together).
Currently we report "stats->rx_dropped = dev->stats.rx_dropped", the
latter being incremented by various entities in the stack. This is not
wrong, but we'd like to move ocelot_get_stats64() in the common ocelot
switch lib which is independent of struct net_device.
To do that, report the hardware RX drop counters instead. These drops
are due to policer action, or due to no destinations. When we have no
memory in the queue system, report this through rx_missed_errors, as
instructed.

The Felix PSFP counters suffer from the same problem as the ocelot
ndo_get_stats64 ones - they are 32-bit, so they can easily overflow and
this can easily go undetected.
Add a custom hook in ocelot_check_stats_work() through which driver
specific actions can be taken, and update the stats for the existing
PSFP filters from that hook.
Previously, vsc9959_psfp_filter_add() and vsc9959_psfp_filter_del() were
serialized with respect to each other via rtnl_lock(). However, with the
new entry point into &psfp->sfi_list coming from the periodic worker, we
now need an explicit mutex to serialize access to these lists.
We used to keep a struct felix_stream_filter_counters on stack, through
which vsc9959_psfp_stats_get() - a FLOW_CLS_STATS callback - would
retrieve data from vsc9959_psfp_counters_get(). We need to become
smarter about that in 3 ways:
- we need to keep a persistent set of counters for each stream instead
of keeping them on stack
- we need to promote those counters from u32 to u64, and create a
procedure that properly keeps 64-bit counters. Since we clear the
hardware counters anyway, and we poll every 2 seconds, a simple
increment of a u64 counter with a u32 value will perfectly do the job.
- FLOW_CLS_STATS also expect incremental counters, so we also need to
zeroize our u64 counters every time sch_flower calls us

To support SPI-controlled switches in the future, access to
SYS_STAT_CFG_STAT_VIEW needs to be done outside of any spinlock
protected region, but it still needs to be serialized (by a mutex).
Split the ocelot->stats_lock spinlock into a mutex that serializes
indirect access to hardware registers (ocelot->stat_view_lock) and a
spinlock that serializes access to the u64 ocelot->stats array.

TSN stream (802.1Qci, 802.1CB) filters are also accessed through
STAT_VIEW, just like the port registers, but these counters are per
stream, rather than per port. So we don't keep them in
ocelot_port_update_stats().
What we can do, however, is we can create register definitions for them
just like we have for the port counters, and delete the last remaining
user of the SYS_CNT register + a group index (read_gix).

Currently phy link up/down interrupt is enabled using the
LAN87xx_INTERRUPT_MASK register. In the lan87xx_read_status function,
phy link is determined using the T1_MODE_STAT_REG register comm_ready bit.
comm_ready bit is set using the loc_rcvr_status & rem_rcvr_status.
Whenever the phy link is up, LAN87xx_INTERRUPT_SOURCE link_up bit is set
first but comm_ready bit takes some time to set based on local and
remote receiver status.
As per the current implementation, interrupt is triggered using link_up
but the comm_ready bit is still cleared in the read_status function. So,
link is always down. Initially tested with the shared interrupt
mechanism with switch and internal phy which is working, but after
implementing interrupt controller it is not working.
It can fixed either by updating the read_status function to read from
LAN87XX_INTERRUPT_SOURCE register or enable the interrupt mask for
comm_ready bit. But the validation team recommends the use of comm_ready
for link detection.
This patch fixes by enabling the comm_ready bit for link_up in the
LAN87XX_INTERRUPT_MASK_2 register (MISC Bank) and link_down in
LAN87xx_INTERRUPT_MASK register.

The stmmac has the possibility to automatically strip the padding/FCS for IEEE
802.3 type frames. This feature is enabled conditionally. Therefore, the stmmac
receive path has to have a determination logic whether the FCS has to be
stripped in software or not.
In fact, for DSA this ACS feature is disabled and the determination logic
doesn't check for it properly. For instance, when using DSA in combination with
an older stmmac (pre version 4), the FCS is not stripped by hardware or software
which is problematic.
So either add another check for DSA to the fast path or simply disable ACS
feature completely. The latter approach has been chosen, because most of the
time the FCS is stripped in software anyway and it removes conditionals from the
receive fast path.

Add the following statistics:
RX successfully decrypted MACsec packets:
macsec_rx_pkts : Number of packets decrypted successfully
macsec_rx_bytes : Number of bytes decrypted successfully
Rx dropped MACsec packets:
macsec_rx_pkts_drop : Number of MACsec packets dropped
macsec_rx_bytes_drop : Number of MACsec bytes dropped
TX successfully encrypted MACsec packets:
macsec_tx_pkts : Number of packets encrypted/authenticated successfully
macsec_tx_bytes : Number of bytes encrypted/authenticated successfully
Tx dropped MACsec packets:
macsec_tx_pkts_drop : Number of MACsec packets dropped
macsec_tx_bytes_drop : Number of MACsec bytes dropped
The above can be seen using:
ethtool -S <ifc> |grep macsec

Add offload support for MACsec SecY callbacks - add/update/delete.
add_secy is called when need to create a new MACsec interface.
upd_secy is called when source MAC address or tx SC was changed.
del_secy is called when need to destroy the MACsec interface.

MACsec driver need to distinguish to which offload device the MACsec
is target to, in order to handle them correctly.
This can be done by attaching a metadata_dst to a SKB with a SCI,
when there is a match on MACsec rule.
To achieve that, there is a map between fs_id to SCI, so for each RX SC,
there is a unique fs_id allocated when creating RX SC.
fs_id passed to device driver as metadata for packets that passed Rx
MACsec offload to aid the driver to retrieve the matching SCI.

Rx flow steering consists of two flow tables (FTs).
The first FT (crypto table) have one default miss rule so non MACsec
offloaded packets bypass the MACSec tables.
All others flow table entries (FTEs) are divided to two equal groups
size, both of them are for MACsec packets:
The first group is for MACsec packets which contains SCI field in the
SecTAG header.
The second group is for MACsec packets which doesn't contain SCI,
where need to match on the source MAC address (only if the SCI
is built from default MACsec port).
Destination MAC address, ethertype and some of SecTAG fields
are also matched for both groups.
In case of match, invoke decrypt action on the packet.
For each MACsec Rx offloaded SA two rules are created: one with SCI
and one without SCI.
The second FT (check table) has two fixed rules:
One rule is for verifying that the previous offload actions were
finished successfully.
In this case, need to decap the SecTAG header and forward the packet
for further processing.
Another default rule for dropping packets that failed in the previous
decrypt actions.
The MACsec FTs are created on demand when the first MACsec rule is
added and destroyed when the last MACsec rule is deleted.
