Original code attempts to retry PLOGIs to fcports that are FCP_TARGETs only. If the driver never performed a successful PLOGI/PRLI, the port-type would never be assigned, and the relogin logic would silently drop the request (and thus the port would not be recognized and registered). The fix is relatively straightforward, drop the FCP_TARGET-only check. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
