Hi, I'm hunting an issue when setting mtu failed for dwmac-sun8i driver. Basically adding more debug shows that in stmmac_change_mtu tx_fifo_size is 0 and in this case EINVAL is reported. Isaw there was fix for similar driver dwmac-sunxi driver by: 806fd188ce2a4f8b587e83e73c478e6484fbfa55
IIRC dwmac-sun8i should get tx and rx fifo size from dma but seems it's not the case. I'm using 5.4 kernel LTS release. Any ideas?
