 I got some new informations about this problem. We noticed that it was
 triggered by 3 specific customers which all had Linksys BEFSR41 routers.
 It seems that forcing an mtu of 1472 on it fix the problem. So maybe
 there's a problem with mtu size negotiation with this router? It would be
 nice to fix the FreeBSD side of this in order to cope with these router
 models... I don't know what's wrong exactly but try with this kind of
 router, hardware version 4.0 and it should do the same thing after some
 hours.
