This series adds support to the Speed downshift, Fast Link Failure 2,
set drivers for Microsemi PHYs.
Patch 1/4: Link Speed downshift:
For operation in cabling environments that are incompatible with
1000BAST-T, VSC8531 device provides an automatic link speed
downshift operation. When enabled, the device automatically changes
its 1000BAST-T auto-negotiation to the next slower speed after
a set number of failed attempts at 1000BAST-T.
This feature is useful in setting up in networks using older cable
installations that include only pairs A and B, and not pairs C and D.
Patch 2/4: Fast Link Failure 2:
VSC8531 Fast Link Failure 2 feature enables the PHY to indicate the
onset of a potential link failure in < 100 usec for 100BASE-TX
operation. FLF2 is supported through the MDINT (active low) pin.
All these features tested on Beaglebone Black with VSC 8531 PHY.
