However, it does send its own FLOGI that lpfc ACCs. The target then establishes the port IDs by sending a PLOGI. lpfc PLOGI_ACCs and starts the RPI registration for DID 0x000001. The target then sends a LOGO to the fabric DID. lpfc is currently treating the LOGO from the fabric DID as a link down and cleans up all the ndlps. The ndlp for DID 0x000001 is put back into NPR and discovery stops, leaving the port in stuck in bypassed mode. Change lpfc behavior such that if a LOGO is received for the fabric DID in PT2PT topology skip the lpfc_linkdown_port() routine and just move the fabric DID back to NPR.
