Subject: [PATCH] brcmfmac: avoid maybe-uninitialized warning in
brcmf_cfg80211_start_ap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
A bugfix added a sanity check around the assignment and use of the
'is_11d' variable, which looks correct to me, but as the function is
rather complex already, this confuses the compiler to the point where
it can no longer figure out if the variable is always initialized
correctly:
brcm80211/brcmfmac/cfg80211.c: In function ‘brcmf_cfg80211_start_ap’:
brcm80211/brcmfmac/cfg80211.c:4586:10: error: ‘is_11d’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This adds an initialization for the newly introduced case in which
the variable should not really be used, in order to make the warning
go away.
Fixes: b3589dfe0212 ("brcmfmac: ignore 11d configuration errors")

Subject: [PATCH] brcmfmac: proto: add callback for queuing TX data
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far our core code was calling brcmf_fws_process_skb which wasn't
a proper thing to do. If case of devices using msgbuf protocol fwsignal
shouldn't be used. It was an unnecessary extra layer simply calling
a protocol specifix txdata function.
Please note we already have txdata callback, but it's used for calls
between bcdc and fwsignal so it couldn't be simply used there.
This makes core code more generic (instead of bcdc/fwsignal specific).

Subject: [PATCH] brcmfmac: update beacon IE after bss up and clear when AP
stopped
Firmware doesn't update beacon/Probe Response vendor IEs correctly when
bss is down, so we move brcmf_config_ap_mgmt_ie after BSS up. And host
driver should clear IEs when AP stopped so that the IEs in host side will
be synced with in firmware side.
