The Altera 10-Gbps Ethernet MAC implements the 10-Gbps Ethernet MAC in
accordance with the IEEE 802.3 2005 specification. This module handles the flow of
data between a client and Ethernet network via a 10-Gbps Ethernet PHY. In the Tx
direction, the MAC accepts client frames, inserts an interpacket gap (IPG), preamble,
start of frame delimiter (SFD), headers, and checksums before passing them to the
PHY. The PHY encodes the MAC frame as required for reliable transmission over the
media to the remote end. Similarly, in the receive direction, the MAC accepts frames
via a PHY, performs checks, generates statistics, strips out the preamble and SFD, and
passes the rest of the frame to the client.
The MAC includes the following interfaces:

The Avalon-MM interface provides host access to the MAC and PHY configuration,
status, MAC, statistics counters registers, and external PHY device registers via the
MDIO interface.
