Hi all:

This series tries to implement eBPF socket filter for tun. This could
be used for implementing efficient virtio-net receive filter for
vhost-net.

Thanks

Changes from V2:
- fix typo
- remove unnecessary double check

Changes from V1:
- trim more bytes if vlan tag is existed to make sure the packet
  length does not exceed what is allowed by the filter.

Jason Wang (2):
  tuntap: rename struct tun_steering_prog to struct tun_prog
  tun: allow to attach ebpf socket filter
