Hi Vladimir, sorry for the delay, I somehow missed your email back in July. > Olimex OLinuXino-A64's ethernet does not work reliably by default. > > It needs the CONFIG_GMAC_TX_DELAY=4 workaround mentioned here: > https://linux-sunxi.org/Olimex_A20-OLinuXino-Lime2#GMAC_quirks Mmh, I am a bit confused: how is this supposed to work? CONFIG_GMAC_TX_DELAY is only used in gmac.c, which is only for the A20 GMAC, but is not used or even built for the A64. When I build an image for a64-olinuxino-emmc_defconfig, I get the exact same binary with and without this patch. So how does this fix anything?
