target: Enable WRITE_INSERT emulation in target_execute_cmd
This patch enables WRITE_INSERT emulation in target_execute_cmd() in order to locally generate DIF PI before submitting the WRITE to the underlying backend device. This is required for fabric drivers that currently don't support DIF over-the-wire, in order to inact with backend devices that have hardware (IBLOCK) or software (FILEIO + RAMDISK) support for handling T10 PI. v2 changes: - Convert to sbc_dif_generate() usage (Sagi) Reviewed-by: Sagi Grimberg <sagig@mellanox.com> Cc: Martin K.
