Hi Jakub Kicinski,

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.

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

Thank you for your guidance.

Regards
Siang
