> 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.
