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.

This patch set is on top of
https://lore.kernel.org/all/20240423035746.699466-1-danielj@nvidia.com/ ,
so patchwork may cause warnings.

Heng Qi (3):
  virtio_net: enable irq for the control vq
  virtio_net: fix possible dim status unrecoverable
  virtio_net: improve dim command request efficiency
