Maybe Alex had something else in mind but we have many virtual interfaces
plus physical interfaces in vswitch use case. Possibly thousands.

virtual interfaces towards many VMs is certainly good use case
that we need to address.
we'd still need to copy the packet from memory of one vm into another,
right? so per packet allocation strategy for virtual interface can
be anything.

Sounds like you already have patches that do that?
Excellent. Please share.
