The following small patch enables PF_RING to work with bonding devices.
The problem was, the ring is enabled on e.g. device bond0 but
the packet is received on a slave device, so the skb doesn't contain the
device name of the ring_netdev device. Therefore no packet was added to
the ring. The patch seems to work, packets are now captured with
pf_ring enabled tcpdump on device bond0.
But i don't know if i missed something.
Cheers,
Michael
