Hey Joe,
Can you help me understand where the fip->ctlr_src_addr gets updated
after we have claimed a FCID? As far as I can tell we're setting it in
fcoe_interface_setup and fcoe_interface_setup, but not anywhere around
the time we call update_mac in the fcoe_ctlr_vn_timeout work thread.
We're using the fip->ctlr_src_addr to send the CLAIM after update_mac,
but I'm not sure it's being updated.
Thanks, //Rob
