| H A D | virtio_net.c | 8958f574 Thu Sep 24 10:59:18 CDT 2009 Rusty Russell <rusty@rustcorp.com.au> virtio_net: return NETDEV_TX_BUSY instead of queueing an extra skb.
This effectively reverts 99ffc696d10b28580fe93441d627cf290ac4484c
"virtio: wean net driver off NETDEV_TX_BUSY".
The complexity of queuing an skb (setting a tasklet to re-xmit) is
questionable, especially once we get rid of the other reason for the
tasklet in the next patch.
If the skb won't fit in the tx queue, just return NETDEV_TX_BUSY.
This is frowned upon, so a followup patch uses a more complex solution.
