Subject: virtio_net: Call dev_kfree_skb_any instead of dev_kfree_skb.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=85e945253955f399c2aacd220423a5e298e963b8;p=linux-beck.git

virtio_net: Call dev_kfree_skb_any instead of dev_kfree_skb.

Replace dev_kfree_skb with dev_kfree_skb_any in start_xmit which can
be called in hard irq and other contexts.

start_xmit only frees skbs that it is dropping.
