Subject: [PATCH] brcmfmac: proto: add callback for queuing TX data
|
|
MIME-Version: 1.0
|
|
Content-Type: text/plain; charset=UTF-8

|
So far our core code was calling brcmf_fws_process_skb which wasn't
|
|
a proper thing to do. If case of devices using msgbuf protocol fwsignal
|
|
shouldn't be used. It was an unnecessary extra layer simply calling
|
|
a protocol specifix txdata function.
|
|
|
|
Please note we already have txdata callback, but it's used for calls
|
|
between bcdc and fwsignal so it couldn't be simply used there.
|
|
|
|
This makes core code more generic (instead of bcdc/fwsignal specific).
