Monitor mode isn't supported yet with brcmfmac, it's just an early work. This also prepares brcmfmac to work stable with new firmwares which use updated struct for passing STA info. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>

Subject: [PATCH] brcmfmac: update STA info struct to the v5

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.
