Comment 21 for bug 1802691

I'm also experiencing this issue and I'm trying to fix this for days now. The send speed caps out at about 700 Mbps. I'm not seeing any hangs or connection losses though. I'm eager to find a solution for this, as I have to move 50 TB over that server.

What I've tried:
- Kernels: 4.15.58, 4.15.60 from bionic-proposed, 5.3rc6
- ethtool:
"ethool -K enp0s31f6 tso off gso off" doesn't do anything
ethtool doens't even have an option for tso, because "ethtool -k enp0s31f6 | grep tso " doesn't return anything
"ethtool -k enp0s31f6 | grep gso" returns
tx-gso-robust: off [fixed]
tx-gso-partial: off [fixed]
tso is probably already off?
- installed latest driver from intel: no change

I would be really thankful I've anyone has a solution for this.
