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.
