[c-nsp] 3560 vs 4948 for Datacenter / iSCSI

[Simon Hamilton-Wilkes]

The 2nd generation iSCSI HBA's from Qlogic (4050 now, previous were
4010) are pretty nice, and support Jumbo frames.  We're using tons of
iSCSI, with switches from HP unmanaged gigabit through 6500's -
doesn't make any difference as long as Jumbos are supported.
