From: Mustafa Ismail Date: Tue, 6 Dec 2016 21:49:34 +0000 (-0600) Subject: i40iw: Assign MSS only when it is a new MTU X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6b0805c25657f9b702607ed4617c2821343158c0;p=linux-beck.git i40iw: Assign MSS only when it is a new MTU Currently we are changing the MSS regardless of whether there is a change or not in MTU. Fix to make the assignment of MSS dependent on an MTU change.
