-Subject: [PATCH] net: lan78xx: Support auto-downshift to 100Mb/s
-
-Ethernet cables with faulty or missing pairs (specifically pairs C and
-D) allow auto-negotiation to 1000Mbs, but do not support the successful
-establishment of a link. Add a DT property, "microchip,downshift-after",
-to configure the number of auto-negotiation failures after which it
-falls back to 100Mbs. Valid values are 2, 3, 4, 5 and 0, where 0 means
-never downshift.
