4519 # LUN ID limit, but the SCSI midlayer requires this field for the uses
4520 # above. The lpfc driver limits the default value to 255 for two reasons.
4521 # As it bounds the sequential scan loop, scanning for thousands of luns
4522 # on a target can take minutes of wall clock time. Additionally,
4523 # there are FC targets, such as JBODs, that only recognize 8-bits of
4524 # LUN ID. When they receive a value greater than 8 bits, they chop off
4525 # the high order bits. In other words, they see LUN IDs 0, 256, 512,
4526 # and so on all as LUN ID 0. This causes the linux kernel, which sees
4527 # valid responses at each of the LUN IDs, to believe there are multiple
4528 # devices present, when in fact, there is only 1.
4529 # A customer that is aware of their target behaviors, and the results as
