I believe it's possible but not implemented currently. The issue is the
implementation should not be vendor specific.

TUN/TAP has its own automatic flow steering implementation (flow caches).

Flow caches can co-operate with RFS/aRFS now, so there's indeed some
kind of co-operation between host card and guest I believe.
