Florian Fainelli 806fd188ce net: stmmac: dwmac-sunxi: Provide TX and RX fifo sizes ... After commit bfcb813203 ("net: dsa: configure the MTU for switch ports") my Lamobo R1 platform which uses an allwinner,sun7i-a20-gmac compatible Ethernet MAC started to fail by rejecting a MTU of 1536. The reason for that is that the DMA capabilities are not readable on this version of the IP, and there is also no 'tx-fifo-depth' property being provided in Device Tree. The property is documented as optional, and is not provided. Chen-Yu indicated that the FIFO sizes are 4KB for TX and 16KB for RX, so provide these values through platform data as an immediate fix until various Device Tree sources get updated accordingly.
