Subject: [PATCH] brcmfmac: Add DMI nvram filename quirk for PoV TAB-P1006W-232
tablet
The Point of View TAB-P1006W-232 tablet contains quite generic names in
the sys_vendor and product_name DMI strings, without this patch brcmfmac
will try to load: brcmfmac43340-sdio.Insyde-BayTrail.txt as nvram file
which is a bit too generic.
Add a DMI quirk so that a unique and clearly identifiable nvram file
name is used on the PoV TAB-P1006W-232 tablet.

Subject: [PATCH] brcmfmac: fix system warning message during wowl suspend
There is a system warning message, warn_slowpath-fmt, during suspend
while using supplicant join AP and enable wowl feature by IW command.
It's caused by brcmf_pno_remove_request path can't find the reqid.
This fix will not go to remove pno request function if there is no
pno scan.

Subject: [PATCH] brcmfmac: modify __brcmf_err() to take bus as a parameter
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far __brcmf_err() was using pr_err() which didn't allow identifying
device that was affected by an error. It's crucial for systems with more
than 1 device supported by brcmfmac (a common case for home routers).
This change allows passing struct brcmf_bus to the __brcmf_err(). That
struct has been agreed to be the most common one. It allows accessing
struct device easily & using dev_err() printing helper.

Subject: [PATCH] brcmfmac: pass bus to the __brcmf_err() in pcie.c
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This enables dev_err() usage (instead of pr_err()) in the __brcmf_err().
It makes error messages more meaningful and is important for debugging
errors/bugs on systems with multiple brcmfmac supported devices.
All bus files should follow & get updated similarly (soon).

Subject: [PATCH] brcmfmac: support monitor frames with the hardware/ucode
header
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far there were two monitor frame formats:
1) 802.11 frames (with frame (sub)type & all addresses)
2) 802.11 frames with the radiotap header
Testing the latest FullMAC firmwares for 4366b1/4366c0 resulted in
discovering a new format being used. It seems (almost?) identical to the
one known from ucode used in SoftMAC devices which is most likely the
same codebase anyway.
While new firmwares will /announce/ radiotap header support using the
"rtap" fw capability string it seems no string was added for the new
ucode header format.
All above means that:
1) We need new format support when dealing with a received frame
2) A new feature bit & mapping quirks have to be added manually
As for now only an empty radiotap is being created. Adding support for
extracting some info (band, channel, signal, etc.) is planned for the
future.
