Subject: mac80211: fix ipw200 build with kernel < 4.10
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=92a96dd66232953482478b317f857f9475d85e50;p=openwrt%2Fstaging%2Fwigyori.git

mac80211: fix ipw200 build with kernel < 4.10

The __change_mtu() function is only compiled when
CPTCFG_IPW2200_PROMISCUOUS is set, more it to the general area.
