[SCSI] bfa: Fix to allow creation of only 190 vports on CNA.
Brocade CNA currently supports only 190 vports (instead of 191), since there are only 192 unicast cam entries reserved for FCoE. Brocade CNA has a total of 256 unicast cam entries (192 FCoE + 64 LL) 192 cam entries = 1 burned in mac + 1 baseport FPMA mac + 190 vport FPMA macs. Made changes to the code to support only 190 vports. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
