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.

  Please backport as appropriate into Bionic and other releases.
