[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. <peter.p.waskiewicz.jr@intel.com> Signed-off-by: David S. Miller <davem@davemloft.net>
