Subject: forcedeth: Call dev_kfree_skb_any instead of kfree_skb.
X-Git-Tag: firefly_0821_release~176^2~4167^2~96^2~18
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1616566c4fa590d4b2011458408a8b39cd46bcc1;p=firefly-linux-kernel-4.4.55.git

forcedeth: Call dev_kfree_skb_any instead of kfree_skb.

Replace kfree_skb with dev_kfree_skb_any in functions that can
be called in hard irq and other contexts.

Every location changes is a drop making dev_kfree_skby_any appropriate.
