Title:
[nfp] NIC stops transmitting for small MSS values when TSO is enabled
Status in Bionic Backports:
Invalid
Status in linux-firmware package in Ubuntu:
Invalid
Bug description:
Description of problem:
When TCP Segmentation Offload (TSO) is enabled on Netronome Agilio SmartNICs,
the interface TX ring hangs when sending packets that require more than 64
segments to send.
Steps to reproduce:
1. Enable TSO (ethtool -K <intf> tso on)
2. Run an iperf session with a suitably small MSS
Actual results:
The iperf traffic rate drops to zero, after which, the NIC accepts no more TX
packets.
Expected results:
The iperf session should complete normally.
Suggested resolution:
This bug has been fixed in version 2.0.4 of the Agilio SmartNIC firmware
available in the upstream linux-firmware repository as of commit
2a91ed954213eabc90154ccd682cbfed7195c4b0.

Please backport as appropriate into Bionic and other releases.
