Kristof Provost 36637dd19d bridge: Don't share broadcast packets 
if_bridge duplicates broadcast packets with m_copypacket(), which
creates shared packets. In certain circumstances these packets can be
processed by udp_usrreq.c:udp_input() first, which modifies the mbuf as
part of the checksum verification. That may lead to incorrect packets
being transmitted.

Use m_dup() to create independent mbufs instead.
