From: Rafał Miłecki Date: Thu, 2 Feb 2017 10:23:17 +0000 (+0100) Subject: mac80211: brcmfmac: backport wowlan netdetect fixes X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b622f40249a08165e5fb24ad5ce31fa49becdb72;p=openwrt%2Fstaging%2Fyousong.git mac80211: brcmfmac: backport wowlan netdetect fixes I needed a moment to figure out relation between this patchset and the nl80211: fix validation of scheduled scan info for wowlan netdetect It appears nl80211 commit will go on top of brcmfmac changes so it's safe to backport these patches. One patch that was excluded is commit 2a2a5d1835b6 ("brcmfmac: add .update_connect_params() callback") as it depends on missing commit 088e8df82f91 ("cfg80211: Add support to update connection parameters").
