If you have the time/inclination it might be worth while trying http://people.freebsd.org/~dmlb/bcm-0308252140.tar.gz on current. This code is what I was working on before bcm merged with Stuart's work to form bfe (and hence may not compile straight off). The reason I suggest trying it, is that I developed it on a 10Mbit hub and didn't have any severe hangs with it. If it works we may be able to track down the reason why if_bfe fails. Duncan
