Bit 7: RX_EXT_HDR_REM_INH is set for GFP null headers. When set, the GFP Payload begins right after the tHEC field. When cleared, the four bytes after the tHEC are the Linear Extended Header.

Bit 6: RX_TYPE_HDR_REM_INH is set to inhibit the removal of the received Type Header for test purposes. When set, this field is prepended to the MAC Payload. When cleared, this field is not forwarded through the MII interface.

Bits 5: RX_EHEC_CHECK_INH is set to inhibit the checking of the received eHEC field.

Bits 4: RX_THEC_CHECK_INH is set to inhibit the checking of the received tHEC field.

Bits 3: RX_TYPE_CHECK_INH is set to inhibit the checking of the received Type field.

Bits 2: RX_SPARE_CHECK_INH is set to inhibit the checking of the received Spare field.

Bits 1: RX_DP_CHECK_INH is set to inhibit the checking of the received DP field.

Bits 0: RX_SP_CHECK_INH is set to inhibit the checking of the received SP field.
