Make sure that FILEIO only attempts to use backend DIF emulation
when it's actually enabled at device level.

This patch updates standard INQUIRY, INQUIRY EVPD=0x86, READ_CAPACITY_16

This patch moves the existing target_execute_cmd() check for
cmd-prot_op into it's own function, so it's easier to add
future support for WRITE STRIP.

Hi MKP, Sagi, Co,
This series adds support for internal WRITE_STRIP + READ_INSERT
DIX operations using existing target_core_sbc.c DIF emulation.
It's useful in order for T10-PI fabrics to interoperate between
backend devices that don't have

This patch updates loopback to add a new fabric_prot_type TPG attribute,
used for controlling LLD level protection into LIO when the backend
device does not support T10-PI.
Also, go ahead and set DIN_PASS + DOUT_PASS so target-core knows that
it will
