[net-next,v3,0/4] virtio_net: enable the irq for ctrlq

Message

Heng Qi June 6, 2024, 6:14 a.m. UTC

Ctrlq in polling mode may cause the virtual machine to hang and
occupy additional CPU resources. Enabling the irq for ctrlq
alleviates this problem and allows commands to be requested
concurrently.

Changelog
=========
v2->v3:
  - Use the completion for dim cmds.

v1->v2:
  - Refactor the patch 1 and rephase the commit log.

Heng Qi (4):
  virtio_net: passing control_buf explicitly
  virtio_net: enable irq for the control vq
  virtio_net: change the command token to completion
  virtio_net: improve dim command request efficiency
