Subject: gianfar: Carefully free skbs in functions called by netpoll.
From: "Eric W. Biederman" <[email protected]>
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.
