Subject: [PATCH] brcmfmac: detect firmware support for monitor interface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Many/most of firmwares support creating monitor interface but only the
most recent ones explicitly /announce/ it using a "monitor" entry in the
list of capabilities.
Check for that entry and store internally info about monitor mode
support using a new feature flag. Once we sort out all details of
handling monitor interface it will be used when reporting available
interfaces to the cfg80211.
Later some fallback detecion method may be added for older firmwares.
For now just stick to the "monitor" capability which should be 100%
reliable.

Depending on used build-time options some firmwares may already include
radiotap header in passed monitor frames. Add a new feature flag to
store info about it. It's needed for proper handling of received frames
before passing them up.

Subject: [PATCH] brcmfmac: handle msgbuf packets marked with monitor mode flag
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
New Broadcom firmwares mark monitor mode packets using a newly defined
bit in the flags field. Use it to filter them out and pass to the
monitor interface. These defines were found in bcmmsgbuf.h from SDK.
As not every firmware generates radiotap header this commit introduces
BRCMF_FEAT_MONITOR_FMT_RADIOTAP flag. It has to be has based on firmware
capabilities. If not present brcmf_netif_mon_rx() will assume packet is
a raw 802.11 frame and will prepend it with an empty radiotap header.
This new code is limited to the msgbuf protocol at this point. Adding
support for SDIO/USB devices will require some extra work (possibly a
new firmware release).

That struct is passed by a firmware when querying for STA info. Flags

These new defines may allow passing more info to the cfg80211 in the
future. They had been obtained from Broadcom's SDK file wlioctl_defs.h
used by DD-WRT.

Subject: [PATCH] brcmfmac: update STA info struct to the v5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
That struct is used when querying firmware for the STA. It seem is has
been changing during the time. Luckily its format seems to be backward
compatible starting with v2 (the only breakage was v1 -> v2).
The version that was supported by brcmfmac so far was v4. It was what
43602a1 and 4366b1 firmwares (7.35.177.56 and 10.10.69.3309 accordingly)
were using. It also seems to be used by early 4366c0 firmwares
(10.10.69.6908 and 10.10.69.69017).
The problem appears when switching to the 10.10.122.20 firmware. It uses
v5 and instead of falling back to v4 when submitted buffer isn't big
enough it fallbacks to the v3.
To receive all v4 specific info with the newest firmware we have to
submit a struct (buffer) that matches v5.

Subject: [PATCH] brcmfmac: specify some features per firmware version
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Some features supported by firmware aren't advertised and there is no
way for a driver to query them. This includes e.g. monitor mode details.
Most firmwares support monitor interface but only the latest ones
/announce/ it with a "monitor" flag in the "cap" iovar. There isn't any
reliable detection method for older firmwares (BRCMF_C_MONITOR was tried
but "it only indicates the core part of the stack supports").
Similarly support for tagging monitor frames and building radiotap
headers can't be reliably detected for all firmwares.
This commit adds table that allows mapping features to firmware version.
It adds mappings for 43602a1 and 4366b1 firmwares from
linux-firmware.git. Both were confirmed to be passing monitor frames.
