Good point.  I changed the paragraph to:

   If you want kernel datapath support for your new field, you also
   need to modify the kernel module for the operating systems you are
   interested in.  This isn't mandatory, since fields understood only
   by userspace work too (with a performance penalty), so it's
   reasonable to start development without it.  If you implement
   kernel module support for Linux, then the Linux kernel "netdev"
   mailing list is the place to submit that support first; please read
   up on the Linux kernel development process separately.  The Windows
   datapath kernel module support, on the other hand, is maintained
   within the OVS tree, so patches for that can go directly to
   ovs-dev.

and applied this to master.
