fcoe: save gateway address when receiving FLOGI request
|
|
|
|
In point-to-point mode, we need to save the source MAC
|
|
from received FLOGI requests to use as the destination MAC
|
|
for all outgoing frames. We stopped doing that at some point.
|
|
|
|
Use the lport_set_port_id method to catch incoming FLOGI frames
|
|
and pass them to fcoe_ctlr_recv_flogi() so it can save the source MAC.
