Subject: [PATCH net-next] be2net: Use dev_consume_skb_any() in the non-drop path


From: Rick Jones <rick.jones2@...com>

The be2net driver was still using dev_kfree_skb_any() in a "normal"
skb freeing path.  This rather clutters perf top -G -e skb_kfree_skb
profiling.

Briefly beaten-on with some netperf TCP_RR tests, but not tried with 
perf because I'm too clueless to get the 3.17.0-rc1 perf and all it 
seems to want onto my "Precise" test system :(
