From 132a3f2bee7600366244097658c4c89ac99a8981 Mon Sep 17 00:00:00 2001 From: Rajesh Borundia Date: Fri, 9 May 2014 02:51:29 -0400 Subject: [PATCH] qlcnic: Allow SR-IOV VF probe in hypervisor. o Add support for SR-IOV VF probe in hypervisor to enable assignment of VFs within hypervisor. o SR-IOV VF can be uplinked to bridge/macvtap device with this change. o Refactor SR-IOV enable/disable code. We cannot take rtnl lock while enabling/disabling SR-IOV as VF probe will take an rtnl lock. o Disable spoofchk by default. Signed-off-by: Rajesh Borundia Signed-off-by: David S.
