The KS8993F has both a static and a dynamic MAC address table. When a Destination Address (DA) look up is
requested, both tables are searched to make a packet forwarding decision. When a Source Address (SA) look up is
requested, only the dynamic table is searched for aging, migration and learning purposes. The static DA look up result
will have precedence over the dynamic DA look up result. If there is a DA match in both tables, the result from the
static table will be used. The static table can be accessed and controlled by an external processor via the SMI, SPI
and I2C interfaces. The external processor performs all addition, modification and deletion of static MAC table entries.
These entries in the static MAC table will not be aged out by the KS8993F.
