  Modified files:
    sys/compat/ndis      kern_ndis.c subr_ndis.c 
    sys/dev/if_ndis      if_ndis.c if_ndisvar.h 
  Log:
  Modify if_ndis.c so that the MiniportISR function runs in ndis_intr()
  and MiniportHandleInterrupt() is fired off later via a task queue in
  ndis_intrtask(). This more accurately follows the NDIS interrupt handling
  model, where the ISR does a minimal amount of work in interrupt context
  and the handler is defered and run at a lower priority.
  
  Create a separate ndis_intrmtx mutex just for the guarding the ISR.
  
  Modify NdisSynchronizeWithInterrupt() to aquire the ndis_intrmtx
  mutex before invoking the synchronized procedure. (The purpose of
  this function is to provide mutual exclusion for code that shares
  variables with the ISR.)
  
  Modify NdisMRegisterInterrupt() to save a pointer to the miniport
  block in the ndis_miniport_interrupt structure so that
  NdisSynchronizeWithInterrupt() can grab it later and derive
  ndis_intrmtx from it.
