From fef59ddfe8ab1302b0c999840f5d238c1dcd2497 Mon Sep 17 00:00:00 2001 From: Catherine Sullivan Date: Thu, 11 Dec 2014 07:06:33 +0000 Subject: [PATCH] i40e: Don't exit link event early if link speed has changed Previously we were only checking if the link up state had changed, and if it hadn't exiting the link event routine early. We should also check if speed has changed, and if it has, stay and finish processing the link event.
