NET: hamradio: Fix IP over bpq encapsulation.
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>. Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Cc: <stable@vger.kernel.org> # 4.1 Signed-off-by: David S. Miller <davem@davemloft.net>
