This should be possible on Huntington, Medford or Medford2 chips since these support toggling checksum offload on any given queue dynamically by means of pushing option descriptors. The patch for FreeBSD driver will then need a means to figure out whether the feature can be used, and testing adapter family might not be a good solution. This patch adds a feature bit specifically to indicate support for checksum option descriptors. The new feature bits may have more users in future, apart from the mentioned FreeBSD patch.
