[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


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.

  virtio_net: separate the logic of checking whether sq is full
  virtio_net: add checking sq is full inside xdp xmit
