Port
These bits indicate the port(s) associated with this MAC address. When bit
18 is cleared, a single port is selected. When bit 18 is set, multiple ports are
selected.
MAC Address
These field contains the last 16 bits of the ALR entry that will be written into
the ALR table. They correspond to the last 16 bits of the MAC address. Bit
15 holds the MSB of the last byte (the last bit on the wire). The first 32 bits
of the MAC address are located in the
