Subject: tc: m_tunnel_key: reformat the usage text
X-Git-Tag: v4.13.0~118
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=50907a8245ea37875fb877d6f21f51a1f247b167;p=thirdparty%2Fiproute2.git

tc: m_tunnel_key: reformat the usage text

Adding new tunnel key fields would cause the usage line overflow 80 chars.
Make the usage text similar to other commands.
