>Organization:
A Site ForUs.
>Environment:

	FreeBSD machine with 2 VIA-chip LAN-card

>Description:

	Bridging does not work properly when bpf is opened.

	in vr_rxeof() ( if_vr.c )
	When bpf is opened, a packet to other machines is not passed to
	only the ether_input but also bridging code.

>How-To-Repeat:

	Enable BRIDGE option in the kernel and enable
        sysctl -w net.link.ether.bridge=1
	then, open bpf ( for example, use tcpdump )

>Fix:

	delete checking eh->ether_dhost code in BPF code and BRIDGE code.
	and put it just before the ether_input(ifp, eh, m);
