Log Message:
Add some workarounds which use EMI register or EEE related:
- PCH only: Add workaround for link disconnects on a busy hub in half duplex.
- PCH and PCH2 only: Set MSE higher to enable link to stay up when noise is
high.
- PCH2 only: Drop link after 5 times MSE threshold was reached.
- PCH2 only: Set EEE LPI Update Timer to 200usec.
- For PCH2 and newer: When connected at 10Mbps half-duplex, some parts are
excessively aggressive resulting in many collisions. To avoid this, increase
the IPG and reduce Rx latency in the PHY.
- For I21[789] and if EEE is enabled: Disable LPLU if both link partners
support 100BaseT EEE and 100Full is advertised on both ends of the link, and
enable Auto Enable LPI since there will be no driver to enable LPI while in
Sx.
