some changes that may break on a quick diff:
static void rtl8169_irq_mask_and_ack(struct rtl8169_private *tp)
{
rtl_irq_disable(tp);
- rtl_ack_events(tp, 0xffff);
+ rtl_ack_events(tp, 0xffffffff);
static void rtl_set_rx_mode(struct net_device *dev)
{
+ u32 rx_mode = AcceptBroadcast | AcceptMyPhys | AcceptMulticast;
+ /* Multicast hash filter */
+ u32 mc_filter[2] = { 0xffffffff, 0xffffffff };
struct rtl8169_private *tp = netdev_priv(dev);
- u32 mc_filter[2]; /* Multicast hash filter */
- int rx_mode;
- u32 tmp = 0;
+ u32 tmp;
....
static void rtl_hw_start_*
- if (tp->dev->mtu <= ETH_DATA_LEN)
- rtl_tx_performance_tweak(tp, PCI_EXP_DEVCTL_READRQ_4096B);
if we can compile a kernel directly from kernel.org we can revert some
of these commits and test which one is causing that issue. but i found
not yet a manual how to compile using mainline-sources directly.
config is (at least in 18.4) /boot/config-5.3.0-59-generic

Title:
ubuntu 20.4 - retransmitts with r8169
Status in linux package in Ubuntu:
Incomplete
Bug description:
Hi,
i run some network-tests (iperf3) and noticed massive retransmitts in
ubuntu 20.4 with kernel 5.4.0-29. I'm using module r8169 for network-
adapter
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 15)
if i boot my ubuntu 18.4 and did same iperf-test (same hardware, same
network configuration, other client is not rebooted) i have not these
retransmitts.

on the other side i see dropped packets, maybe flowcontrol-related?

but maybe flowcontrol is not working...
also driver reports flowcontrol is enabled...
