On some boards there is no eeprom to hold the nvram, in this case instead
a board specific nvram is loaded from /lib/firmware. On most boards the
macaddr=... setting in the /lib/firmware nvram file is ignored because
the wifi/bt chip has a unique MAC programmed into the chip itself.
But in some cases the actual MAC from the /lib/firmware nvram file gets
used, leading to MAC conflicts.
The MAC addresses in the troublesome nvram files seem to all come from
the same nvram file template, so we can detect this by checking for
the template nvram file MAC.
Detect that the default MAC address is being used and replace it
with a random MAC address to avoid MAC address conflicts.
Note that udev will detect this is a random MAC based on
/sys/class/net/wlan0/addr_assign_type and then replace this with
a MAC based on hashing the netdev-name + the machine-id. So that
the MAC address is both guaranteed to be unique per machine while
it is still the same/persistent at each boot (assuming the
default Link.MACAddressPolicy=persistent udev setting).

Use the new DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to
handle the .suspend/.resume callbacks.
These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards.
Some other functions not directly called by the .suspend/.resume
callbacks, but still related to PM were also taken outside #ifdef
guards.
The advantage is then that these functions are now always compiled
independently of any Kconfig option, and thanks to that bugs and
regressions are easier to catch.

The for loop in brcmf_of_probe() would ideally end with something like
"i <= strlen(board_type)" instead of "i < board_type[i]". But
fortunately, the two are equivalent.
Anyway, it's simpler to use strreplace() instead.

Marcin Szycik says:
Add support for dissecting PPPoE and PPP-specific fields in flow dissector:
PPPoE session id and PPP protocol type. Add support for those fields in
tc-flower and support offloading PPPoE. Finally, add support for hardware
offload of PPPoE packets in switchdev mode in ice driver.
Example filter:
tc filter add dev $PF1 ingress protocol ppp_ses prio 1 flower pppoe_sid \
1234 ppp_proto ip skip_sw action mirred egress redirect dev $VF1_PR
Changes in iproute2 are required to use the new fields (will be submitted
soon).
ICE COMMS DDP package is required to create a filter in ice.

Currently, userland has no method to query which timestamping features
are supported by the peak_usb driver (aside maybe of getting RX
messages and observe whether or not hardware timestamps stay at zero).
The canonical way to add hardware timestamp support is to implement
ethtool_ops::get_ts_info() in order to advertise the timestamping
capabilities and to implement net_device_ops::ndo_eth_ioctl() as
requested in [1]. Currently, the driver only supports hardware RX
timestamps [2] but not hardware TX. For this reason, the generic
function can_ethtool_op_get_ts_info_hwts() and can_eth_ioctl_hwts()
can not be reused and instead this patch adds pcan_get_ts_info() and
peak_eth_ioctl().

Tools based on libpcap (such as tcpdump) expect the SIOCSHWTSTAMP
ioctl call to be supported. This is also specified in the kernel doc
[1]. The purpose of this ioctl is to toggle the hardware timestamps.
Currently, CAN devices which support hardware timestamping have those
always activated. can_eth_ioctl_hwts() is a dumb function that will
always succeed when requested to set tx_type to HWTSTAMP_TX_ON or
rx_filter to HWTSTAMP_FILTER_ALL.

Add function can_ethtool_op_get_ts_info_hwts(). This function will be
used by CAN devices with hardware TX/RX timestamping support to
implement ethtool_ops::get_ts_info. This function does not offer
support to activate/deactivate hardware timestamps at device level nor
support the filter options (which is currently the case for all CAN
devices with hardware timestamping support).
The fact that hardware timestamp can not be deactivated at hardware
level does not impact the userland. As long as the user do not set
SO_TIMESTAMPING using a setsockopt() or ioctl(), the kernel will not
emit TX timestamps (RX timestamps will still be reproted as it is the
case currently).
Drivers which need more fine grained control remains free to implement
their own function, but we foresee that the generic function
introduced here will be sufficient for the majority.

Because of the loopback feature of socket CAN, hardware TX timestamps
are nothing else than the hardware RX timespamp of the corresponding
loopback packet. This patch simply reuses the hardware RX timestamp.
The rationale to clone this timestamp value is that existing tools
which rely of libpcap (such as tcpdump) expect support for both TX and
RX hardware timestamps in order to activate the feature (i.e. no
granular control to activate either of TX or RX hardware timestamps).

(aside maybe of getting RX messages and observe whether or not
hardware timestamps stay at zero).
The canonical way for a network driver to advertised what kind of

This patch only targets the CAN drivers which *do not* support
hardware timestamping. For each of those CAN drivers, implement the
get_ts_info() using the generic ethtool_op_get_ts_info().
This way, userland can do:
| $ ethtool --show-time-stamping canX
to confirm the device timestamping capacities.
N.B. the drivers which support hardware timestamping will be migrated
in separate patches.

TX timestamps were added to the can_put_echo_skb() function of can_dev

and as such do not offer TX timestamping.
While it could be arguable whether TX timestamps are really needed for
virtual interfaces, we prefer to still add it so that all CAN drivers,

TX timestamps were added to the can_put_echo_skb() function of can_dev
modules in [1]. However, janz-ican3 does not rely on that function but
instead implements its own echo_skb logic. As such it does not offer
TX timestamping.
Add a call to skb_tx_timestamp() in the ican3_put_echo_skb() function
so that the module now supports TX software timestamps.

onboard_hub_power_on() already ensures the reset pulse width delay, so
there is no need to wait right after requesting GPIO as well.

In the driver there are parts of code where the prefix `slc' is used and
others where the prefix `slcan' is used instead. The patch replaces
every occurrence of `slc' with `slcan', except for the netdev functions
where, to avoid compilation conflicts, it was necessary to replace `slc'
with `slcan_netdev'.
The patch does not make any functional changes.

Taking inspiration from the drivers/net/can/can327.c driver and at the
suggestion of its author Max Staudt, I removed legacy stuff like
`SLCAN_MAGIC' and `slcan_devs' resulting in simplification of the code
and its maintainability.
The use of slcan_devs is derived from a very old kernel, since slip.c
is about 30 years old, so today's kernel allows us to remove it.
The .hangup() ldisc function, which only called the ldisc .close(), has
been removed since the ldisc layer calls .close() in a good place
anyway.
The old slcanX name has been dropped in order to use the standard canX
interface naming. The ioctl SIOCGIFNAME can be used to query the name of
the created interface. Furthermore, there are several ways to get stable
interfaces names in user space, e.g. udev or systemd-networkd.
The `maxdev' module parameter has also been removed.

The driver uses the string "slcan" to populate
tty_ldisc_ops::name. KBUILD_MODNAME also evaluates to "slcan". Use
KBUILD_MODNAME to get rid on the hardcoded string names.
Similarly, the pr_info() and pr_err() hardcoded the "slcan"
prefix. Define pr_fmt so that the "slcan" prefix gets automatically
added.

The preferred nomenclature is pnv_, not powernv_, but rng.c used
powernv_ for some reason, which isn't consistent with the rest. A recent
commit added a few pnv_ functions to rng.c, making the file a bit of a
mishmash. This commit just replaces the rest of them.

Commit 3c783b83bd0f ("net: dsa: mv88e6xxx: get rid of SPEED_MAX setting")
stopped relying on SPEED_MAX constant and hardcoded speed settings
for the switch ports and rely on phylink configuration.
It turned out, however, that when the relevant code is called,
the mac_capabilites of CPU/DSA port remain unset.
mv88e6xxx_setup_port() is called via mv88e6xxx_setup() in
dsa_tree_setup_switches(), which precedes setting the caps in
phylink_get_caps down in the chain of dsa_tree_setup_ports().
As a result the mac_capabilites are 0 and the default speed for CPU/DSA
port is 10M at the start. To fix that, execute mv88e6xxx_get_caps()
and obtain the capabilities driectly.

The S25HL-T/S25HS-T family is the Infineon SEMPER Flash with Quad SPI.
These Infineon chips support volatile version of configuration registers
and it is recommended to update volatile registers in the field application
due to a risk of the non-volatile registers corruption by power interrupt.
Add support for volatile QE bit.
For the single-die package parts (512Mb and 1Gb), only bottom 4KB and
uniform sector sizes are supported. This is due to missing or incorrect
entries in SMPT. Fixup for other sector sizes configurations will be
followed up as needed.
