  Log:
  The procedure of raceless switching between polling mode and
  taskqueued interrupt mode is going to be quite complex. Since
  the polling mode is considered legacy feature for em(4) driver,
  the decision is made to make polling and new interrupt handler
  mutually exclusive, selected at compile time.
  
  If kernel is compiled with DEVICE_POLLING, the fast taskqueued
  interrupt handler code is disabled and the em_poll() and legacy
  em_intr() functions are enabled. Otherwise, legacy functions
  are disabled and only em_intr_fast() code is compiled.
