  SVN rev 211596 on 2010-08-22 01:39:09Z by yongari
  
  It seems all Broadcom controllers have a bug that can generate UDP
  datagrams with checksum value 0 when TX UDP checksum offloading is
  enabled.  Generating UDP checksum value 0 is RFC 768 violation.
  Even though the probability of generating such UDP datagrams is
  low, I don't want to see FreeBSD boxes to inject such datagrams
  into network so disable UDP checksum offloading by default.  Users
  still override this behavior by setting a sysctl variable or loader
  tunable, dev.bge.%d.forced_udpcsum.
  
  I have no idea why this issue was not reported so far given that
  bge(4) is one of the most commonly used controller on high-end
  server class systems. Thanks to andre@ who passed the PR to me.
