If the problem is caused by missing TXCFG_AUTO_FIFO bit in TxConfig, as the register difference would suggest, then you can try applying the following patch (hack) on top of 4.18.8 that is already patched with commit f74dd480cf4e: --- a/drivers/net/ethernet/realtek/r8169.c +++ b/drivers/net/ethernet/realtek/r8169.c @@ -5043,7 +5043,8 @@ { /* Set DMA burst size and Interframe Gap Time */ RTL_W32(tp, TxConfig, (TX_DMA_BURST << TxDMAShift) | - (InterFrameGap << TxInterFrameGapShift)); + (InterFrameGap << TxInterFrameGapShift) + | TXCFG_AUTO_FIFO); } static void rtl_set_rx_max_size(struct rtl8169_private *tp) This hack will probably only work properly on RTL_GIGA_MAC_VER_40 or later NICs. Before running any tests please verify with "ethtool -d enp3s0" that TxConfig register now contains 0x4f000f80, as it did in the old, working driver version. If this does not help then a bisection will most likely be needed. > Thanks in advance, > David Arendt Maciej
