Subject: [PATCH] NET: hamradio: Fix IP over bpq encapsulation.
Date: Sat, 4 Jul 2015 11:22:30 +0200 [thread overview]
Message-ID: <20150704092230.GN5255@linux-mips.org> (raw)
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>.
