The 8-bit protocol value to match with the incoming frame's IP header protocol field.
Reserved bits. Write as 0.
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:IP Snooping function
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 protocol value occurs,
the frame is processed as defined by the mode setting.
All other bits of the register are interpreted by the IP snooping function only if the enable bit is set. Otherwise
the settings are ignored.
Defaults to 0 upon reset.
Reserved bits. Write as 0.
