Subject: [PATCH] brcmfmac: support STA info struct v7
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
The newest firmwares provide STA info using v7 of the struct. As v7
|
|
isn't backward compatible, a union is needed.
|
|
|
|
Even though brcmfmac does not use any of the new info it's important to
|
|
provide the proper struct buffer. Without this change new firmwares will
|
|
fallback to the very limited v3 instead of something in between such as
|
|
v4.
