  1472bytes UDP payload will cause ~1200HZ interrupt (ticks controls TX HC)
  1bytes UDP payload will cause ~5100HZ interrupt (bds controls TX HC)
- Restore Broadcom's default RX ticks settings (18).  Set RX bds to 12.
  This should be able to restore TCP stream RX performance.  Add a note
  in comment that setting RX ticks to any value above 13 will make RX bds
  control RX HC.  It is found out by using following method:
  Assume for bulk data RX, RX ticks should always control RX HC if RX bds is
  relative large.  So RX bds is set to 128, which should be large enough but
  less than the limit (255).  Other side of this test TXes 1472bytes payload
  UDP datagrams.  The result:
      RX ticks    Interrupt rate
         12          livelock
         13           47800
         14            1270
         15            1270
         16            1270
         17            1270
         18            1270
         19            1270
         20            1270
         30            1270
  Linux bnx2 says the RX ticks unit is microsecond, while it looks incorrect.
  FreeBSD bce(4) does not have any comment about the RX ticks setting.
  We probably need to find a dynamic RX bds tuning mechanism to prevent system
  from being livelocked if full speed tiny packets are injected.
