From 1909a42ad4ad297c4cee989c9e9dd5f99e37af4b Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Sun, 21 Jun 2015 12:07:33 +0000 Subject: [PATCH] mac80211: backport some brcmfmac patches MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
