  Modified files:
    sys/dev/em           if_em.c if_em.h 
  Log:
  - Introduce two more stat counters, counting number of RX
    overruns and number of watchdog timeouts.
  - Do not log(9) RX overrun events, since this pessimizes
    things under load [1].
  - Do not increase if->if_oerrors in em_watchdog(), since
    this leads to counter slipping back, when if->if_oerrors
    is recalculated in em_update_stats_counters(). Instead
    increase watchdog counter in em_watchdog() and take it
    into account in em_update_stats_counters().
