[PATCH] lan743x: Use correct MAC_CR configuration for 1 GBit speed
From: Roelof Berg
Date: Wed Jun 03 2020 - 17:55:37 EST
Corrected the MAC_CR configuration bits for 1 GBit operation. The data
sheet allows MAC_CR(2:1) to be 10 and also 11 for 1 GBit/s speed, but
only 10 works correctly.
Devices tested:
Microchip Lan7431, fixed-phy mode
Microchip Lan7430, normal phy mode
