+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.
