Patch prefixes

When looking at Patchwork, it is no always clear to distinct if the patch is for MPTCP tree ("internal review") for -net or for -net-next or for netdev ML directly.

We are then using different tags:

• [PATCH mptcp-next]: for net-next (now or later):
  • If it has a Fixes: tag, it will be applied in the "fixes for net-next" section
  • If not in "new feature for net-next" section
  • except if there are specific instructions in the comments
• [PATCH mptcp-net]: for net (ASAP):
  • to be applied in "fixes for net" section, at the bottom of the tree
  • except if there are specific instructions in the comments
• [PATCH net-next]: sent to netdev ML for net-next and MPTCP ML is in CC
  • Patchwork status can be Deferred.
• [PATCH net]: sent to netdev ML for -net and MPTCP ML is in CC
  • Patchwork status can be Deferred.

Please try to think about that ;-)
