I may miss something, but it looks to me the indirection table should be
implemented through a map as well? Since it was accessible by guest and qemu
need to trap the access and convert it to eBPF map updating?
makes sense, I'll convert it to map structure.
This looks tricky as well, should we search the BPF_LD and replace the imm?
Hmm yes this approach is better I guess.
I believe those bpf helpers should be moved to tap-linux.c.
All of them? I actually thought about moving them to a standalone
file in the virtio-net.c dir.
Can you explain the motive for this?
