Summary: FreeBSD 4.3 Broadcast IP datagrams not looping on Broadcom GigE card.

Are these packets that fail part of a IP fragment? m_copy does not copy the hwassist flags. we see the same problem with multicast packets. Bill Fenner wrote a simular multicast patch before FreeBSD 4.5-RELEASE, but even that fix has not been included into the tree yet either. In ip_output, we should either we need to copy the hwassist flag in _copy or in the code that follows a m_copy, or force the checksum calculations. if your packets are not part of a fragment, then let me know. --mark tinguely.
