Current implementation for netmap(4) tun(4) support adds a pseudo ethernet header, src/dst ethernet addresses being all zero'ed. This seems to cause problems with hashing in the consumer applications (i.e. Sensei / Suricata ). Proposed patch fixes this by simply adding a more proper ethernet pseudo header. This got tested by us and by a Sensei user who reported this.

Ranges don't belong to anyone so I guess this is fine. Debating inclusion in 21.1 today (window is still open). Cheers, |
