is firmware already takes care of it in our new feature scan

Pull networking updates from David Miller:
"Highlights:
1) Support more Realtek wireless chips, from Jes Sorenson.
2) New BPF types for per-cpu hash and arrap maps, from Alexei
Starovoitov.
3) Make several TCP sysctls per-namespace, from Nikolay Borisov.
4) Allow the use of SO_REUSEPORT in order to do per-thread processing
of incoming TCP/UDP connections. The muxing can be done using a
BPF program which hashes the incoming packet. From Craig Gallek.
5) Add a multiplexer for TCP streams, to provide a messaged based
interface. BPF programs can be used to determine the message
boundaries. From Tom Herbert.
6) Add 802.1AE MACSEC support, from Sabrina Dubroca.
7) Avoid factorial complexity when taking down an inetdev interface
with lots of configured addresses. We were doing things like
traversing the entire address less for each address removed, and
flushing the entire netfilter conntrack table for every address as
well.
8) Add and use SKB bulk free infrastructure, from Jesper Brouer.
9) Allow offloading u32 classifiers to hardware, and implement for
ixgbe, from John Fastabend.
10) Allow configuring IRQ coalescing parameters on a per-queue basis,
from Kan Liang.
11) Extend ethtool so that larger link mode masks can be supported.
From David Decotigny.
12) Introduce devlink, which can be used to configure port link types
(ethernet vs Infiniband, etc.), port splitting, and switch device
level attributes as a whole. From Jiri Pirko.
13) Hardware offload support for flower classifiers, from Amir Vadai.
14) Add "Local Checksum Offload". Basically, for a tunneled packet
the checksum of the outer header is 'constant' (because with the
checksum field filled into the inner protocol header, the payload
of the outer frame checksums to 'zero'), and we can take advantage
of that in various ways. From Edward Cree"

Same chip is being used by WLAN as well as bluetooth
drivers. Each driver needs to check during initialisation
if firmware is already active or it needs to be freshly
downloaded. If one driver has started downloading the
firmware, other finds the winner flag as false.
mwifiex_check_fw_status() checks firmware status and also
check if WLAN is the winner for firmware downloading.
Once we detect that other interface is downloading
the firmware, we call this routine again with max
poll count to wait until firmware is ready.
This patch splits the routine to avoid checking
winner status unnecessarily multiple times and ensures
that correct messages are displayed to user.

have gpio and gap modified by user.
This patch fixes the problem.

Sometimes AP sends TDLS setup response as AMSDU packet.
As driver doesn't parse it and update peer station's 11n
capability in this case, AMPDU doesn't get setup.
This patch calls mwifiex_process_tdls_action_frame() in
AMSDU Rx path to fix the problem.

When hostapd is killed with Ctrl+C before cac get completed,
stop_ap handler will not be called, thus priv->wdev.cac_started
flag remains set.
Hostapd restart attempt will be failed in this case with device
busy error. This patch aborts cac in del_station handler to
handle this corner case.

Wildcard prefix bytes are ignored while downloading packet
pattern to firmware. As packet offset is not adjusted
accordingly firmware end up matching the pattern at wrong
offset. The packet offset is corrected in this patch.
