From 0e512bfc2c0cd6072387092f8d1ac8e1a758965b Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 18 Nov 2010 03:12:30 +0000 Subject: igbvf: force link checking when mailbox timeout has occurred This change forces the link down when a mailbox timeout has occurred. Previously it was possible for a mailbox timeout to occur but for the interface to stay up. The problem with this was that it became possible for an interface to stay up and miss multiple requests resulting in a possible issue since the interface will be running in an unknown state.
