From 09c4e56b3cddecb6cac70339dcec63ed1b4e18c2 Mon Sep 17 00:00:00 2001 From: Kamil Krawczyk Date: Wed, 4 Jun 2014 20:41:43 +0000 Subject: [PATCH] i40e/i40evf: add ASQ write back timeout variable to AQ structure Add new variable defining ASQ command write back timeout to allow for dynamic modification of this timeout. Initialize it on AQ initialize routine with default value, vary it on device ID.
