The simple_tx_hash() function we currently have in
net/core/dev.c is very rudimental and doesn't handle
routing and firewall scenerios very well.

This is really cool! Thanks Dave!

The next 4 patches attempt to cure that.  The end result
is:

1) The RX queue selection of the input device seeds the
  TX queue selection for that SKB.

2) Locally generated packets seed the TX queue using
  skb->sk->sk_hash

One thing that I've been thinking about is that it would be
really useful if we guaranteed that every inbound packet carried
a hash with it.  This could be used to help subsequent processing
such as routing, netfilter, etc. since they all need to make
decisions based on flows.

Cheers,
