  Log:
  - Correct collision counter for BCM5705+.  This register is read/clear.
  - Correct RX packet drop counter for BCM5705+.  This register is read/clear
  and it wraps very quickly under heavy packet drops because only the lower
  ten bits are valid according to the documentation.  However, it seems few
  more bits are actually valid and the rest bits are always zeros[1].
  Therefore, we don't mask them off here.  To get accurate packet drop count,
  we need to check the register from bge_rxeof().  It is commented out for now,
  not to penalize normal operation.  Actual performance impact should be
  measured later.
  - Correct integer casting from u_long to uint32_t.  Casting is not really
  needed for all supported platforms but we better do this correctly[2].
