Subject: SME: MLD: Fix byte order for the link reconfig MLE control field
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3e4782549dd25731172cbfcb180fad2a7e165b39;p=thirdparty%2Fhostap.git

SME: MLD: Fix byte order for the link reconfig MLE control field

This is a 16-bit bit little endian field and as such, needs to be
converted to host byte order before comparison.

Fixes: e5ea30feefa3 ("SME: MLD: Handle reconfiguration Multi-Link element")
