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>
