This avoids to send two packets (FlowMod & PacketOut).
OF v1.3.1 (the specification most switch vendors implemented) mentions
in A.3.4.1 on page 65 that this is a valid way to avoid two packets.

The match_to_str() function in ryu/lib/ofctl_v1_0.py does not convert

Note: It wasn't clear to me which NXM stands for "Extensible" or
"Extended". I chose the latter because it's in the primary
specification. (nicira-ext.h)

Also, run pep8 in a separate environment.
The way to specify python versions might seem awkward.
(Well, it seems so to me.)
But it follows one of examples referenced in the official
documentation:

I'm not quite sure how it happens to work with the current
test environment. But the current coding doesn't work when
running via testr probably due to different PYTHONPATH.

In generally, iBGP session is established between loopback interfaces.
Therefore, we need to specify loopback interface as neighbour_source_address.
This parameter is just like update-source command in cisco router.

In openflow spec 1.2 and 1.3.4, in order to match only packets without a VLAN tag,
the value of OFPXMT_OFB_VLAN_VID must be set to OFPVID_NONE (0x0000).
Old API of ofproto_v1_2/3_parser is now enabled to setting the oxm_value to OFPVID_NONE(0x0000) as follows:
e.g.)
match = ofproto_v1_2_parser.OFPMatch()
match.set_vlan_vid_none()

According to RFC 2545, both a global address and a link-local address
can be sent as a next_hop address in BGPUpdate message.
Since the link-local address is not needed in Ryu BGP,
Ryu BGP ignore it if the address family is IPv6 unicast.
