Bug description:
  Bug 1800664 introduced checksum offload and TSO support for HiNIC adapters. 
While that did improve performance in short iperf runs, longer runs were later 
found to show a significant regression in performance:

  [Test Case]
  iperf -c -P5

  Revert the offending patch.

  [Regression Risk]
  This is reverting a patch, returning the driver to 18.10 GA behavior.
