Title: [nfp] NIC stops transmitting for small MSS values when TSO is enabled Status in Bionic Backports: New Status in linux-firmware package in Ubuntu: New 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. https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux- firmware.git/commit/?id=2a91ed954213eabc90154ccd682cbfed7195c4b0 Please backport as appropriate into Bionic and other releases.
