From 1ee240e31d4c0a5fd37ebaf064ca1f6cb6adcb6f Mon Sep 17 00:00:00 2001 From: "Mintz, Yuval" Date: Thu, 1 Jun 2017 15:29:11 +0300 Subject: [PATCH] qed: No need to reset SBs on IOV init Since we're resetting the IGU CAM each time we initialize the PF device, there's no need to reset the VF SBs again when initializing IOV.
