Since 1d5da757da860a6916adbf68b09e868062b4b3b8 (ax25: Stop using magic
neighbour cache operations.) any attempt to transmit IP packets over
a bpqether device will result in a message like "Dead loop on virtual
device bpq0, fix it urgently!"
Fix suggested by Eric W. Biederman <ebiederm@xmission.com>.
