Subject: Remove unneeded set-MTU operation from drivers
X-Git-Tag: hostap_0_7_1~491
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0715247aa80d50cd96b59919bebaa13eba5bd7db;p=thirdparty%2Fhostap.git

Remove unneeded set-MTU operation from drivers

This code was copied from driver_hostap.c where it is used with the
special wlan#ap interface. It was not supposed to be used to change
the MTU for a normal data interface.
