[PATCH net, stable v1 0/3] add checking sq is full inside xdp xmit

[Xuan Zhuo <xuanzhuo@xxxxxxxxxxxxxxxxx>]

If the queue of xdp xmit is not an independent queue, then when the xdp
xmit used all the desc, the xmit from the __dev_queue_xmit() may encounter
the following error.

net ens4: Unexpected TXQ (0) queue failure: -28

This patch adds a check whether sq is full in XDP Xmit.

Thanks.

v1:
    1. rename to check_sq_full_and_disable
    2. reorder some funcs to avoid declaration

Xuan Zhuo (3):
  virtio_net: reorder some funcs
  virtio_net: separate the logic of checking whether sq is full
  virtio_net: add checking sq is full inside xdp xmit
