Subject: [PATCH] brcmfmac: print firmware reported general status errors
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
Firmware may report general errors using a special message type. Add
|
|
basic support for it by simply decoding & printing an error number.
|
|
|
|
A sample situation in which firmware reports a buf error:
|
|
CONSOLE: 027084.733 no host response IOCTL buffer available..so fail the request
|
|
will now produce a "Firmware reported general error: 9" on the host.
