New Revision: 267270
URL: http://svnweb.freebsd.org/changeset/base/267270

Log:
  Add new protocol method pru_ready. The method is used to wake up
  a socket after pru_send with not ready data had been done before.
  
  The arguments should be pointer to mbuf that is already in the
  socket buffer, and a count of mbufs to set ready.
