Note: it is possible to set both the compare source/dest bits. The result is OR'ed, meaning
if any of the fields match the compare value, the frame is processed as defined by the mode
bits.

The 16-bit port number to compare within the TCP or UDP header of a frame.
Reserved bits. Write as 0.
When set, the TCP or UDP source port number field within the frame is compared with the compare value
provided in 31:16.
When set, the TCP or UDP destination port number field within the frame is compared with the compare
value provided in 31:16.
Defines the forwarding that should occur, when an IP frame is received and the protocol field matches the
protocol value (see bits 15:8).
Bits 2:1:
00: forward frame to designated management port only 01: copy to management port and forward normally
10: discard
Note: the management port is defined in register MGMT_CONFIG.
When set (1) the entry contains valid data and the function is active. If a match with the TCP/UDP destination
port value occurs, the frame is processed as defined by the mode setting.
All other bits of the register are interpreted by the snooping function only if the enable bit is set. Otherwise
the settings are ignored.
When written with 0 will also force bits 3,4 to 0.
Defaults to 0 upon reset.
