ASM_DIR
Advertise Asymmetric Pause Direction register bit.
This register bit is used in conjunction with Pause
(Register bit 4.10)
0 = Link partner is not capable of asymmetric
pause

Pause
Advertise to link partner that Pause operation is
desired (IEEE 802.3x Standard)

100BASE-T4
0 = 100BASE-T4 capability is not available
1 = 100BASE-T4 capability is available
The IXF1104 MAC does not support 100BASE-T4,
but allows this register bit to be set to advertise in
auto-negotiation sequence for 100BASE-T4
operation. If this capability is desired, an external
100BASE-T4 transceiver can be switched in.
