Pause
Threshold
When a pause frame is sent, an internal timer checks
when a new pause frame must be scheduled for
transmission to keep the link partner in pause mode.
The pause threshold value is the minimum time to
send before the earlier pause frame is aged out.

MaxFrameSize
The maximum frame size the MAC can receive or
transmit without activating any error counters, and
without truncation.
The maximum frame size is internally adjusted by +4
if VLAN is tagged.

RGMII Speed
These bits are used to define the speed of the
IXF1010 operation.
01 = 100 Mbps - RGMII TX_CLK is 25 MHz
1x = 1 Gbps - RGMII TX_CLK is 125 MHz
