Hi:

This series tries to optimize vhost_net polling at two points:

- Stop rx polling for reduicng the unnecessary wakeups during
  handle_rx().
- Conditonally enable tx polling for reducing the unnecessary
  traversing and spinlock touching.

Test shows about 17% improvement on rx pps.

Please review

Changes from V1:
- use vhost_net_disable_vq()/vhost_net_enable_vq() instead of open
  coding.
- Add a new patch for conditionally enable tx polling.

Jason Wang (2):
  vhost_net: stop polling socket during rx processing
  vhost_net: conditionally enable tx polling
