Subject: brcmfmac: obtain iftype for firmware-signal descriptor lookup
X-Git-Tag: v3.10-rc1~66^2~51^2^2~70
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a7965fbb9108aef004829caf7a80129e452f76de;p=platform%2Fkernel%2Flinux-exynos.git

brcmfmac: obtain iftype for firmware-signal descriptor lookup

The function brcmf_fws_find_mac_desc() determines the descriptor
associated with a sk_buff for firmware-signalling. It needs the
interface type to do that. For this a helper function is added in
wl_cfg80211.c.
