Station address logic (SAL)
The station address logic module examines the destination address field of incoming
frames, and filters the frames before they are stored in the Ethernet front-end
SAL Station address logic
Performs destination address filtering.
MII Media Independent Interface
Provides the interface from the MAC core to a PHY that supports the MII
(as described in the IEEE 802.3 standard).
