  Modified files:
    sys/dev/netif/et     if_et.c 
  Log:
  - Increase RX coalesced packets from 32 to 129 to avoid being livelocked when
    ~1.48Mpps 64bytes packets are injected.
  - Increase RX coalescing ticks from 20 to 25 and correct the comment about its
    unit: it is 4us instead of 10us (thanks go to jsg at openbsd.org for giving me
    the informational material :).
  
  # An interrupt is generated if
  # (RX pkt count > ET_RX_INTR_NPKTS) || (timer > ET_RX_INTR_DELAY)
  #
  # I thought the interrupt generation condition was
  # (RX pkt count > ET_RX_INTR_NPKTS) && (timer > ET_RX_INTR_DELAY)
