Both applied, thanks.

There are a few things that I'm aware of that also should be taken
care of to be compatible with recent kernels.  They're a little more
subtle because they don't cause compilation problems:

* RPS hash.  We should clear skb->rxhash when we make a modification
that could affect it.  This could come up in either actions like
changing the IP address or tunneling.

* vlan acceleration.  In 2.6.37 we can start receiving packets with
vlan tags in the skb->vlan_tci field but we don't currently look for
them there.  We also need to take into account acceleration when
modifying/stripping a vlan tag.
