  Log:
  This patch improves fine-grained locking for the ng_ppp node.
  Till now node's transmit path was completely unprotected
  and so wasn't thread safe in multilink mode. It's receive path was
  declared as WRITER as the simpliest protection method but it
  reduces performance when compression or encryption enabled.
