L4SP0 | Layer 4 Source Port Number Field When the L4PEN0 bit is reset and the L4DPM0 bit is set in the (ETH_MACL3L4C0R), this field contains the value to be matched with the TCP Source Port Number field in the IPv4 or IPv6 packets. When the L4PEN0 and L4DPM0 bits are set in (ETH_MACL3L4C0R), this field contains the value to be matched with the UDP Source Port Number field in the IPv4 or IPv6 packets. |
L4DP0 | Layer 4 Destination Port Number Field When the L4PEN0 bit is reset and the L4DPM0 bit is set in the (ETH_MACL3L4C0R), this field contains the value to be matched with the TCP Destination Port Number field in the IPv4 or IPv6 packets. When the L4PEN0 and L4DPM0 bits are set in (ETH_MACL3L4C0R), this field contains the value to be matched with the UDP Destination Port Number field in the IPv4 or IPv6 packets. |
