Subject: [PATCH net-next 0/2] net: phy: Add Downshift, FLF2 drivers for Microsemi


From: Raju Lakkaraju <Raju.Lakkaraju@...rosemi.com>

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.
