I want a process to know when the hardware address of br0 changes. I looks like br_stp_change_bridge_id() in br_stp_if.c is where the change occurs. Is there anyone out there who can cook up a simple patch to send a netlink message (the same kind of message that is sent when SIOCSIFHWADDR happens on a device that supports it), or is this a problem that requires major restructuring to solve? I am using kernel 2.4.21, but br_stp_change_bridge_id() looks mostly the same in 2.6. Thank you. -- Dan Eble <dane@aiinet.com> _____ .
