Subject: [PATCH] brcmfmac: enlarge buffer size of caps to 512 bytes
|
|
|
|
The buffer size of return of cap iovar is greater than 256 bytes in some
|
|
firmwares. For instance, the return size of cap iovar is 271 bytes in 4373
|
|
13.10.246.79 firmare. It makes feature capability parsing failed because
|
|
caps buffer is default value.
|
|
So we enlarge caps buffer size to 512 bytes and add the error print for
|
|
cap iovar error.
