Expose more signature setting parameters. We modify the signature API to allow usage of some new execution parameters relevant to data integrity feature. This patch modifies ib_sig_domain structure by: - Deprecate DIF type in signature API (operation will be determined by the parameters alone, no DIF type awareness) - Add APPTAG check bitmask (for input domain) - Add REFTAG remap (increment) flag for each domain - Add APPTAG/REFTAG escape options for each domain The mlx5 driver is modified to follow the new parameters in HW signature setup. At the moment the callers (iser/isert) hard-code new parameters (by DIF type). In the future, callers will retrieve them from the scsi command structure.
