From 566cfd8f0e049a0647f94714f913e2a975dc464f Mon Sep 17 00:00:00 2001 From: Simon Arlott Date: Thu, 26 Jul 2007 00:09:55 -0700 Subject: [PATCH] [IPV6]: Don't update ADVMSS on routes where the MTU is not also updated The ADVMSS value was incorrectly updated for ALL routes when the MTU is updated because it's outside the effect of the if statement's condition.
