Description
Send packets with unknown destination MAC addresses to
specified port(s) in bits [2:0] of this register.
0 = disable
1 = enable
Reserved
Do not change the default values.
Specify which port(s) to send packets with unknown
destination MAC addresses. This feature is enabled by bit
[7] of this register.
An ‘1’ includes a port.
An ‘0’ excludes a port.
