From a6cc0cfa72e0b6d9f2c8fd858aacc32313c4f272 Mon Sep 17 00:00:00 2001 From: John Fastabend Date: Wed, 6 Nov 2013 09:54:46 -0800 Subject: net: Add layer 2 hardware acceleration operations for macvlan devices Add a operations structure that allows a network interface to export the fact that it supports package forwarding in hardware between physical interfaces and other mac layer devices assigned to it (such as macvlans). This operaions structure can be used by virtual mac devices to bypass software switching so that forwarding can be done in hardware more efficiently.
