Subject: mac80211: fix build on UML
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0aa351196ae3c5262b38a61dab6d1672b4070a2f;p=openwrt%2Fstaging%2Fnbd.git

mac80211: fix build on UML

A duplicate include guard prevents inclusion of barrier.h in UML build and this prevents mac80211 from building.

This patch re-enables mac80211 hwsim and renames the include guard.

See https://lists.openwrt.org/pipermail/openwrt-devel/2015-June/033614.html for details.
