From 44b82dded19be8f09d0fee373f395935cef79c41 Mon Sep 17 00:00:00 2001 From: Greg Rose Date: Sat, 21 Apr 2012 00:54:28 +0000 Subject: [PATCH] ixgbe: Fix bogus error message If the VF sends a MACVLAN request with index of zero then it is not actually trying to add a filter. Check the index value and only indicate that operation is not allowed when the VF is actually trying to add a filter.
