  Log:
  pr_ctlinput is usually called when certains types of ICMP packets are received.
  However, the processing of ICMP packets happens in netisr0, which means the
  thread context, in which pr_ctlinput is called, is not correct.  To handle this
  following two fixes are applied:
  - Add pr_ctlport to protosw and ip6protosw, which could be used to locate
    correct msgport to call pr_ctlinput for specific protocol
  - All necessary information needed by pr_ctlinput are gather into one netmsg,
    and this netmsg is delivered synchronously (some information is on the stack)
  
  Note for new protocol implementation:
  pr_ctlinput and pr_ctlport should be both NULL or both non-NULL.
