    sys/kern             kern_poll.c 
    sys/net              if_var.h netisr.c netisr.h 
  Log:
  The schednetisr() routine is supposed to be MP and interrupt safe, but wasn't
  because it allocated its messages.  Instead of allocating a message use a
  fixed message in the netisr structure.
  
  Get rid of #ifdef SMP/#error.  DEVICE_POLLING now works on SMP builds.
  
  Implement an emergency polling enable function to try to keep the system
  operational in a degraded state if interrupt routing is blown.  NOTE: only
  vr0 uses the feature at the moment, and DEVICE_POLLING must be enabled.
