From 943258b6a3b1fe4b54dd579b9e2e5bec1d9af407 Mon Sep 17 00:00:00 2001 From: Hante Meuleman Date: Thu, 12 Dec 2013 11:59:02 +0100 Subject: [PATCH] brcmfmac: Add definition of new protocol layer msgbuf. A new protocol layer msgbuf will be added in the future. This change makes it possible to select the desired layer by the bus driver. USB and SDIO will select BCDC. At the moment nothing is being done with this information.
