Did you kill the peer connection? shut/no shut etc - changing the mtu on
the fly won't help. The error msg below means the mtu is still 1500 at the
time the peer was exchanging capabilities.
I just tested this and the error msg disappears when you set the mtu
higher, 1600 for example and I understand this to fix the problem from
internal information even though I do not have netbios hosts handy.
