Subject: [net-next 02/13] ixgbe: Fix return value from macvlan filter function

From: Greg Rose <gregory.v.rose@...el.com>

The function to set the macvlan filter should return success or failure
instead of the index of the filter.  The message processing function was
misinterpreting the index as a non-zero return code indicating failure and
NACKing MAC filter set messages that actually succeeded.
