Minor nits:
- Ethernet driver patches should usually be sent to netdev@...r.kernel.org.
  Their state is thus tracked at
  http://patchwork.ozlabs.org/project/netdev/list/

- The more specific about the target branch, the better:
  [PATCH net 1/1] via-rhine: blah
  -> patch against davem's bugfixes branch
  [PATCH net-next 19/73] foo: more balh
  -> patch against davem's dev branch

- davem will take care of -stable propagation
