Subject: spider_net: Call dev_consume_skb_any instead of dev_kfree_skb.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=20eca054e9d90db3d6181e35d7425dfb79d5cd00;p=linux-beck.git

spider_net: Call dev_consume_skb_any instead of dev_kfree_skb.

Replace dev_kfree_skb with dev_consume_skb_any in
spider_net_release_tx_chain which can be called in hard irq and other
contexts.

dev_consume_skb_any was choosen as it preserves the current
dev_kfree_skb semantics (dev_kfree_skb is consume_skb) and
is because it is correct most of the time as most packets
will have been successfully transmitted not dropeed.
