From 3d885e39219095ec5788026a1256dff61c86fa29 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 6 Feb 2012 17:27:52 +0000 Subject: sfc: Add support for TX MAC filters On Siena each TX queue can be configured to send only packets for which there is a TX MAC filter that matches the source MAC address, queue ID, and optionally VID. This will be used to implement the 'spoofchk' feature for SR-IOV virtual functions.
