From 3fb1d8d2dad35f5094350c175b778b78df894284 Mon Sep 17 00:00:00 2001 From: Franky Lin Date: Fri, 16 Dec 2011 18:37:04 -0800 Subject: brcm80211: fmac: move driver up status to struct brcmf_bus Driver up/down status to network interface need to be shared by common layer and bus layer. Move it to bus interface structure brcmf_bus as part of the fullmac bus interface refactoring.
