8260. For 'ib_srpt.ko' module, which built from source before
[2], the default maximum initiator to target IU is 2116.

Each SCSI host can represent a connection to another SRP target, and the
max_it_iu_size parameter can differ per target. So I think this variable
should be moved into struct srp_target_port instead of being global. See
also srp_max_it_iu_len().
Thanks,
Bart.
