Looks like there is a problem in the interaction between the ssh2 protocol in Openssh and the bpf0 device. Any ideas?

When using ssh1 not prob all good, but when I use ssh2(ie ssh -2 hostname) and then run trafshow or tcpdump I noticed a crazy amount of traffic generated, ie a constant flow of 40-50K per sec or more just by the ssh session, yet under ssh1 it only gen's about 1-3K per sec. I tried this on an older version of ssh and this does not re-occur. Can someone else try this and tell me what you get....ie ssh from any box to a FreeBSD4.4 stable box using ssh -2 hostname. Then do a 'trafshow port 22' and see what your bytes/sec is after a 1min run or so. >From what I can tell it is a problem with sshd not the client. Thanks.
