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.
