The LAN9118 features mask us used to enable/disable certain features
advertised by the device during auto-negotiation.

Juno and TC2 do not support full duplex communication properly, causing
intermittent failures, so we disable them using the mask.

The feature mask used is effectively:
  ~(PHYANA_10BASETFD | PHYANA_100BASETXFD);

The constants for the bit masks are defined here:
  EmbeddedPkg/Drivers/Lan9118Dxe/Lan9118DxeHw.h
