Subject: [PATCH net-next] bonding: drop_monitor aware
Date: Wed, 13 Jun 2012 17:30:07 +0200	[thread overview]
Message-ID: <1339601407.22704.380.camel@edumazet-glaptop> (raw)

From: Eric Dumazet <edumazet@google.com>

When packets are dropped in TX path, its better to use kfree_skb()
instead of dev_kfree_skb() to give proper drop_monitor events.

Also move the kfree_skb() call after read_unlock() in bond_alb_xmit()
and bond_xmit_activebackup()
