Subject: xen-netfront: Call dev_kfree_skb_any instead of dev_kfree_skb.
X-Git-Tag: v3.15-rc1~113^2~96^2~4

xen-netfront: Call dev_kfree_skb_any instead of dev_kfree_skb.

Replace dev_kfree_skb with dev_kfree_skb_any in xennet_start_xmit
which can be called in hard irq and other contexts.  xennet_start_xmit
only fress skbs which it drops.
