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?
ethtool reports "Link partner advertised pause frame use: Symmetric"
but maybe flowcontrol is not working...
also driver reports flowcontrol is enabled...
