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.
