Subject: [PATCH net] Documentation: bareudp: update iproute2 sample commands
Date: Mon, 20 Jul 2020 17:46:58 +0200 [thread overview]
Message-ID: <57d0fff72970fdc7d49ab969f940438728f10754.1595259799.git.gnault@redhat.com> (raw)
bareudp.rst was written before iproute2 gained support for this new
type of tunnel. Therefore, the sample command lines didn't match the
final iproute2 implementation.

+The multiproto mode allows bareudp tunnels to handle several protocols of the
