Has anybody tried setting STMMAC_FLAG_RX_CLK_RUNS_IN_LPI. https://elixir.bootlin.com/linux/latest/source/drivers/net/ethernet/stmicro/stmmac/dwmac-qcom-ethqos.c#L816 The problem description makes it sound like the hardware does not like the clock being turned off. Setting this flag might fix that. Andrew
