Subject: [PATCH net-next 10/10] gianfar: Carefully free skbs in functions called by netpoll.

From: [email-masked] (Eric W. Biederman)
Date: Tue, 11 Mar 2014 14:20:26 -0700

netpoll can call functions in hard irq context that are ordinarily
called in lesser contexts.  For those functions use dev_kfree_skb_any
and dev_consume_skb_any so skbs are freed safely from hard irq
context.
