Do not connect in HE mode if the AP does not support LDPC with more
than 20M bandwidth or in 20M if it advertise the MCS11 support.
Connect in 11ac/11n mode if the LDPC check fails.

PANIC_ON_BUG is currently enabled for all WLAN builds. While a customer
can, and should, disable PANIC_ON_BUG for end user builds, this can be
easily overlooked. Disable PANIC_ON_BUG by default on pure performance
builds, to avoid accidentally crashing end user devices. Customers can
opt-in to PANIC_ON_BUG as needed for validation on performance builds.

The Make variable $(M) must point to the directory that contains the
module source code (which includes this Makefile). It can either be an
absolute or a relative path. If it is a relative path, then it must be
relative to the kernel source directory (KERNEL_SRC). An absolute path
can be obtained very easily through $(shell pwd). Generating a path
relative to KERNEL_SRC is difficult and we accept some outside help by
letting the caller override the variable $(M). Allowing a relative path
for $(M) enables us to have the build system put output/object files
(.o, .ko.) into a directory different from the module source directory.

hdd_softap_hard_start_xmit has cds_ssr_protect so prevent it running at
point of cds_wait_for_external_threads_completion in wlan_hdd_remove,
but after that hdd_softap_hard_start_xmit still inject in, it will
cause race condition between tx and unloading deinit.
Fix it by checking driver load/unload status at the beginning of
__hdd_softap_hard_start_xmit, and similar change for sta mode.

In STA+SAP concurrency, when the STA connection is in progress or set_key
is in progress, the set_hw_mode command to SME is queued and would be
processed only after the connection is complete. Meanwhile, when a stop
SAP is received and SAP Dissassociate STA is triggered from HDD, the
command is queued in SME and cannot be processed until STA connection
is done. The add_key command from the supplicant is also stuck as the
previous stop_ap command is in progress leading to a deadlock. When the
AP sends deauth to the STA due to 4 Way Handshake failure, the STA is
reset and then the stop SAP command proceeds, followed by another
connection for the STA.
Disconnect STA interface first if connection or key exchange is in progress
and then stop SAP interface to prevent this deadlock condition.

When channel list contains all channels from channel 1 to channel
165 and ch width is 80MHz, the channel to be selected as part of
ACS algorithm should be a 5GHz channel as 2.4GHz channels does not
support 80MHz but 2.4GHz channel gets selected with channel
width as 40MHz. Similarly when ch width is 160Mhz, the 160Mhz bonding
can be made only by 36-64 and 100-128 channels but 2.4Ghz channel or
some other 5Ghz channel gets selected as a result of ACS algorithm.
Assign max weight to all the 2.4GHz channels in 80Mhz and to all 2.4 Ghz
channels and 5Ghz channels not in the range 36-64 and 100-128 in 160 Mhz
so that only a valid channel is selected after the ACS algorithm is
completed.

Remove panic after peer_delete timeout and fail corresponding peer
operation. Peer reference count can be taken by kworker thread which
may get pre-empted by other higher priority threads or stuck, leading
to delay in releasing reference. This delay cannot be completely
removed, hence rather than panic after timeout, enhance logging and
fail corresponding peer operation.
