[PATCH 04/16] lpfc: Fix SLI3 hba in loop mode not discovering devices

[James Smart <jsmart2021@gmail.com>]

When operating in private loop mode, PLOGI exchanges are racing and
the driver tries to abort it's PLOGI. But the PLOGI abort ends up
terminating the login with the other end causing the other end to
abort its PLOGI as well. Discovery never fully completes.

Fix by disabling the PLOGI abort when private loop and letting the
state machine play out.
