From 4b3afc6e386bdacbce8326afcf8040a632050d3a Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Sat, 15 Mar 2014 18:22:47 -0700 Subject: [PATCH] via-rhine: Call dev_kfree/consume_skb_any instead of dev_kfree_skb. Replace dev_kfree_skb with dev_kfree_skb_any in rhine_start_tx which can be called in hard irq and other contexts. Packets are only freed in rhine_start_tx if they are dropped. Replace dev_kfree_skb with dev_consume_skb_any in rhine_tx that can be called in hard irq and other contexts. rhine_tx handles successfully transmitted packets. Signed-off-by: "Eric W.
