4 Subject: [PATCH] brcmfmac: support STA info struct v7
5 MIME-Version: 1.0
6 Content-Type: text/plain; charset=UTF-8
7 Content-Transfer-Encoding: 8bit
8  
9 The newest firmwares provide STA info using v7 of the struct. As v7
10 isn't backward compatible, a union is needed.
11  
12 Even though brcmfmac does not use any of the new info it's important to
13 provide the proper struct buffer. Without this change new firmwares will
14 fallback to the very limited v3 instead of something in between such as
15 v4.
