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

This is a subject that came up in the virtio BOF session at OLS. I decided to go forward and implement something that I like, based on the latest virtio proposal at the time, which was draft III. It's not a drop-in replacement, because it's missing a host implementation. I first started my own, which is not done yet, but wanted to do one for lguest and one for emulated PCI next. It's
