From: Rafał Miłecki Date: Sun, 21 Jun 2015 12:07:33 +0000 (+0000) Subject: mac80211: backport some brcmfmac patches X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1909a42ad4ad297c4cee989c9e9dd5f99e37af4b;p=openwrt%2Fstaging%2Frmilecki.git mac80211: backport some brcmfmac patches There are two important patches in this patchset: updating read pointer quicker & rework of .get_station(). There are few more upstream patches that are p2p-related and weren't backported in this commit.
