From 80feaacb8a6400a9540a961b6743c69a5896b937 Mon Sep 17 00:00:00 2001 From: "Peter P. Waskiewicz Jr" Date: Fri, 20 Apr 2007 16:05:39 -0700 Subject: [AF_PACKET]: Add option to return orig_dev to userspace. Add a packet socket option to allow the orig_dev index to be returned to userspace when passing traffic through a decapsulated device, such as the bonding driver. This is very useful for layer 2 traffic being able to report which physical device actually received the traffic, instead of having the encapsulating device hide that information. The new option is called PACKET_ORIGDEV. Signed-off-by: Peter P. Waskiewicz Jr. Signed-off-by: David S.
