net/bridge: Add 'hairpin' port forwarding mode
This patch adds a 'hairpin' (also called 'reflective relay') mode
port configuration to the Linux Ethernet bridge kernel module.
A bridge supporting hairpin forwarding mode can send frames back
out through the port the frame was received on.
Hairpin mode is required to support basic VEPA (Virtual
Ethernet Port Aggregator) capabilities.
You can find additional information on VEPA here:

An additional patch 'bridge-utils: Add 'hairpin' port forwarding mode'
is provided to allow configuring hairpin mode from userspace tools.
