You're right, my apologies.
libiscsi_tcp.o is built for CONFIG_ISCSI_TCP, but it's _also_ built for
CONFIG_SCSI_CXGB3_ISCSI and CONFIG_SCSI_CXGB4_ISCSI. I missed that when
I looked at the Makefile and wrongly assumed that CONFIG_ISCSI_TCP was
missing the select.
I'm not sure what the right fix here would be -- should
CONFIG_SCSI_CXGB[34]_ISCSI depend on CONFIG_ISCSI_TCP..? Or should we
add those CRYPTO* selects in there as well?
