This is a bug/feature-request/documentation issues for documenting what is know about Brocade Loopback and E-port behaviour.
Quest
This is a side-quest for acquiring more knowledge. No feature currently depends on this. It would be cool to understand how this is implemented by Brocade to deepen the understanding of real-world FC equipment.
Status
Observed behavior is that the port links up to AC state just fine, but is then sent a Link Reset (LR) at which point the idle-word seems to switch to ARB(AL_PA) with AL_PA=0xEF.
What needs to be done?
Map the 8b/10b traffic that is sent between two different Brocade switches (E-ports)
# TODO: No port status dump for this
Map the 8b/10b traffic that is sent between a loopback on a Brocade switch. (Loopback)

Extra questions
What is this ESC missmatch Fabirc Id message about? Is it because we are linking up the same switch to itself? Try with another switch to figure out maybe.
