Bit	Field	Type	Reset	Description
31:19	RESERVED	NONE	0h	Reserved
18	FH_REMAP_DSCP_V6	R/W	0h	Port 0 FHost (ingress) remap priority to DSCP IPV6 priority (see packet priority handling section for details). 0 - Hardware switch priority IPV6 DSCP priority remapping is disabled. 1 - Hardware switch priority IPV6 DSCP priority remapping is enabled.
17	FH_REMAP_DSCP_V4	R/W	0h	Port 0 FHost (ingress) remap priority to DSCP IPV4 priority (see packet priority handling section for details). 0 - Hardware switch priority IPV4 DSCP priority remapping is disabled. 1 - Hardware switch priority IPV4 DSCP priority remapping is enabled.
16	FH_REMAP_VLAN	R/W	0h	Port 0 receive (ingress) remap priority to VLAN. See priority remapping section for details.
15	FH_ECC_ERR_EN	R/W	0h	Port 0 FHost ECC Error Enable. This bit must be set to enable FHost ECC error operations
14	TH_ECC_ERR_EN	R/W	0h	Port 0 THost ECC Error Enable. This bit must be set to enable THost ECC error operations.
13:4	RESERVED	NONE	0h	Reserved
3	TH_CHECKSUM_EN	R/W	0h	Port 0 THost (egress) Checksum Enable 0 - THost checksum is disabled. 1 - THost checksum is enabled. IPV4/V6 Packets have checksum information (4-bytes) included at the end of the packet data when the chksum_encap descriptor bit is set in the EOP THost buffer descriptor.
2	FH_DSCP_IPV6_EN	R/W	0h	Port 0 FHost IPv6 DSCP enable 0 - Ipv6 DSCP priority mapping is disabled. 1 - Ipv6 DSCP priority mapping is enabled.
1	FH_DSCP_IPV4_EN	R/W	0h	Port 0 FHost IPv4 DSCP enable 0 - Ipv4 DSCP priority mapping is disabled. 1 - Ipv4 DSCP priority mapping is enabled.
0	FH_CHECKSUM_EN	R/W	0h	Port 0 FHost (port 0 ingress) Checksum Enable 0 - FHost checksum is disabled. 1 - FHost checksum is enabled. Four bytes of checksum information can be included at the start of the packet data to be used for checksum packet processing when chksum_encap is set in the SOP FHost buffer descriptor.
