+
+Since Linux 4.7, the enum ieee80211_band is no longer used
+
+This shall cause no problem's since both enums ieee80211_band
+and nl80211_band were added in the same commit:
+https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit?id=13ae75b103e07304a34ab40c9136e9f53e06475c
+
+This patch refactors the references of IEEE80211_BAND_* to NL80211_BAND_*

+Subject: Compile fix with kernel 4.11
+Origin: http://bugs.debian.org/861807
+Forwarded: no
+Reviewed-By: Eduard Bloch <blade@debian.org>
+Last-Update: 2017-05-04
+
+ I use the attached patch to get this module compiled with 4.11. Works
+ for me since last sunday.
+ Apparently https://aur.archlinux.org/cgit/aur.git/tree/linux411.patch?h=broadcom-wl
+ has come with a different patch for the removed last_rx field in
+ netdevice. But judging the commit log
+ https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/patch/include/linux/netdevice.h?id=4a7c972644c1151f6dd34ff4b5f7eacb239e22ee
+ and the fact that last_rx isn't used elsewhere I came up with just
+ ifdef it out.
