For each LLD (cxgb3i and cxgb4i) could it get called more than once? I
mean if you had multiple cxgb3i HBAs could it get called once for each
or is it called just once time for all cxgb3i hbas? If more than once
the cxgbi_iscsi_init call to iscsi_register_transport would fail on the
second call, because the iscsi class would not allow you to register the
same transport twice.
