This function, currently called by WoWLAN flow, polls until specific HW
queues are empty. The polling bit definitions are not totally the same
between WiFi 6 and 7 chips. In addition, the check conditions are also
a little different. So, we differentiate the implementations according to
chip gen.

In queue empty check, one group contains 32 queues. And, the two elements,
wde_qempty_acq_num and wde_qempty_mgq_sel, are number of group and select
of group. To avoid confusing them with queue number and queue selection,
we refine their naming.

DLE stands for Double Link Engine that is used to maintain buffer page.
To avoid linking to wrong pages, we check the used page size during
initialization and stop driver probe if the used size is unexpected.
Currently, we check the page size used by PLE (payload engine) and WDE
(WiFi descriptor engine). For coming WiFi 7 chips, additional reserved
size is added for BB as buffer to run LA mode, so add and check the
reserved size as well.

A dynamic mechanism is usually an algorithm to adjust registers to adapt
to different environment every two seconds. In field, it could get
unexpected result, so we need to stop it and adjust registers manually, and
then fine tune the algorithm.

Add dynamic mechanism EDCCA (Energy Detection Clear Channel Assessment)
in track work. Using a fixed-value threshold will make EDCCA particularly
sensitive and cause failure to transmit under certain circumstances.
Therefore, the threshold is dynamically adjusted to make EDCCA suitable
for any situation.
However, in some cases, we will adjust the EDCCA threshold to the highest
level so that urgent transmissions can be performed successfully, such as
scanning.
Finally, in order to observe the EDCCA report in time, add the EDCCA perIC
register macro and EDCCA HW report analysis. EDCCA logs can be displayed
by using the EDCCA debug mask.

Commit 4b478bf6bdd8 ("wifi: libertas: drop 16-bit PCMCIA support") reworks
the dependencies for config LIBERTAS, and adds alternative dependencies for
USB, SDIO and SPI.
The config option SDIO however does not exist in the kernel tree. It was
probably intended to refer to the config option MMC, which represents
"MMC/SD/SDIO card support" and is used as dependency by various other
drivers that use SDIO.
Fix the dependency to the config option MMC for declaring the requirement
on provision of SDIO support.

syzbot was able to trigger a crash [1] in page_pool_unlist()
page_pool_list() only inserts a page pool into a netdev page pool list
if a netdev was set in params.
Even if the kzalloc() call in page_pool_create happens to initialize
pool->user.list, I chose to be more explicit in page_pool_list()
adding one INIT_HLIST_NODE().
We could test in page_pool_unlist() if netdev was set,
but since netdev can be changed to lo, it seems more robust to
check if pool->user.list is hashed before calling hlist_del().

net: ethernet: Convert to platform remove callback returning void
in (implicit) v1 of this series
(https://lore.kernel.org/netdev/20231117091655.872426-1-u.kleine-koenig@pengutronix.de)
I tried to address the resource leaks in the three cpsw drivers. However
this is hard to get right without being able to test the changes. So
here comes a series that just converts all drivers below
drivers/net/ethernet to use .remove_new() and adds a comment about the
potential leaks for someone else to fix the problem.
See commit 5c5a7680e67b ("platform: Provide a remove callback that
returns no value") for an extended explanation and the eventual goal.
The TL;DR; is to prevent bugs like the three noticed here.
Note this series results in no change of behaviour apart from improving
the error message for the three cpsw drivers from
remove callback returned a non-zero value. This will be ignored.

To simplify the flow in cookie_v[46]_check(), we move such fields'

SYN Cookie handling into cookie_tcp_check(), where we validate the

wait_local_port_listen() helper is defined in diag.sh, mptcp_connect.sh,
mptcp_join.sh and simult_flows.sh, export it into mptcp_lib.sh and
rename it with mptcp_lib_ prefix. Use this new helper in all these
scripts.
Note: We only have IPv4 connections in this helper, not looking at IPv6
(tcp6) but that's OK because we only have IPv4 connections here in diag.sh.

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
check_transfer() and print_file_err() helpers are defined both in
mptcp_connect.sh and mptcp_sockopt.sh, export them into mptcp_lib.sh
and rename them with mptcp_lib_ prefix. And use them in all scripts.
Note: In mptcp_sockopt.sh it is OK to drop 'ret=1' in check_transfer()
because it will be set in run_tests() anyway.

In mptcp_connect.sh we are missing something like "oflag=append"
because this will write "${rem}" bytes at the beginning of the file
where there is already some random bytes. It should write that at
the end.
This patch adds this missing 'oflag=append' flag for 'dd' command in
make_file().

To avoid duplicated code in different MPTCP selftests, we can add
and use helpers defined in mptcp_lib.sh.
The helper get_counter() in mptcp_join.sh and get_mib_counter() in
mptcp_connect.sh have the same functionality, export get_counter() into
mptcp_lib.sh and rename it as mptcp_lib_get_counter(). Use this new
helper instead of get_counter() and get_mib_counter().
Use this helper in test_prio() in userspace_pm.sh too instead of
open-coding.

The value of 'err' will not be only '-EINVAL', but can be '0' in some
cases.
So it's better to rename the label 'remove_err' to 'out' to avoid
confusions.
