Regarding your suggestion of implementing a "wildcard rule,"
are you suggesting the use of an ethtool command similar to the following?

ethtool -U <iface name> flow-type ether action <default queue>

I have a concern that users might be not aware that this nfc rule is having lowest priority,
as the default queue would only take effect when no other filtering rules match.

I believe that ethtool n-tuple rules are expected to be executed in
order. User can use the 'loc' argument to place the rule at the end 
of the table.

Do you see this as a potential issue? If not, I am willing to proceed with
exploring the ethtool options you've mentioned.
