Message-ID: <20120827162930.2969.96733.stgit@gitlad.jf.intel.com> Date: Mon, 27 Aug 2012 09:30:01 -0700 From: Alexander Duyck <alexander.h.duyck@...el.com> To: netdev@...r.kernel.org Cc: davem@...emloft.net, jeffrey.t.kirsher@...el.com Subject: [PATCH] ipv4: Minor logic clean-up in ipv4_mtu In ipv4_mtu there is some logic where we are testing for a non-zero value and a timer expiration, then setting the value to zero, and then testing if the value is zero we set it to a value based on the dst. Instead of bothering with the extra steps it is easier to just cleanup the logic so that we set it to the dst based value if it is zero or if the timer has expired.
