Using the i40e driver with an x710 card is it possible to set up flow
classification rules to filter based on values past the UDP header? I have
a packet counter value in a header past the IPv4 / UDP headers that I would
like to use with ntuple / flow director rules.
Looking at ethtool there seems to be a user defined data and mask but it
looks like the i40e driver doesn't use it or uses it for some
virtualization:

Thanks,
