    sys/dev/bge          if_bge.c 
  - All bge(4) supported hardware is known to support RX/TX checksum offloading,
    except for BGE_CHIPID_BCM5700_B0, which is buggy.
  - All bge(4) supported hardware, has a bug that produces incorrect checksums
    on Ethernet runts. However, in case of a transmitted packet, the latter can
    be padded with zeroes, and the checksum would be correct. (Probably chip
    includes the pad data into checksum). In case of receive, we just don't
    trust checksum data in received runts.
