Looks like somebody forgot to use the _bh spin_lock variant. We ran into a deadlock where br->hello_timer expired while br_stp_disable_br() walked br->port_list.

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

Hi I'm looking for code that implements the 802.1d spanning tree. Do you have an idea where can I download this code?
