When Bit 0 (L3PEN1) and Bit 2 (L3SAM1) are set in
Register 268 (Layer 3 and Layer 4 Control Register 1),
this field contains the value to be matched with
Bits[31:0] of the IP Source Address field in the IPv6
frames. When Bit 0 (L3PEN1) and Bit 4 (L3DAM1)
are set in Register 268 (Layer 3 and Layer 4 Control
Register 1), this field contains the value to be matched
with Bits [31:0] of the IP Destination Address field in
the IPv6 frames. When Bit 0 (L3PEN1) is reset and
Bit 2 (L3SAM1) is set in Register 268 (Layer 3 and
Layer 4 Control Register 1), this field contains the
value to be matched with the IP Source Address field
in the IPv4 frames.
