Duplex
The MAC supports full-duplex or half-duplex depending on the line-side interface that is
configured by the
The duplex of the MAC is set in the

to match the attached PHY duplex for proper IXF1104 MAC operation.
Copper Auto-Negotiation
In the copper MAC, auto-negotiation and all other controls of the PHY devices are achieved
through the MDIO interface, and are independent of the MAC controller. See
MDIO Control and Interface, on page 95
In copper mode, auto-negotiation is accomplished by the attached PHY, not the IXF1104
MAC. Thus, the IXF1104 MAC does not automatically configure the MAC or other blocks in
the device to be consistent with attached PHY auto-negotiation results. This must be
accomplished by the user and system software.
Jumbo Packet Support
The IXF1104 MAC supports jumbo frames. The jumbo frame length is dependent on the
application and the IXF1104 MAC design is optimized for a 9.6 KB jumbo frame length.
Larger lengths can be programmed, but limited system performance may lead to data loss
during certain flow-control conditions
The value programmed into
maximum length frame size the MAC can receive or transmit without activating any error
counters, and without truncation.
TheMax Frame Size (Addr: Port_Index + 0x0F)
value programmed into this register is 0x05EE (1518). The value is internally adjusted by +4
if the frame has a VLAN tag. The overall programmable maximum is 0x3FFF or 16383
bytes.
The register should be programmed to 0x2667 for the 9.6 KB length jumbo frame, optimized
for the IXF1104 MAC. The RMON counters are also implemented for jumbo frame support
