I've had success reverting drivers/net/ethernet/stmicro/ up to and including "stmmac: first frame prep at the end of xmit routine", i.e. top 7 commits. http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/net/ethernet/stmicro?id=0e80bdc9a72df3b31a9fc2012102a6cc8d664e93 > If you share some logs to me I can take a look at them. > Then we can try to check if the problem in on rx or tx path. > I also ask you yo check the axi settings.
