ip.neigh "dump" does not show IPv6 addresses

[ralonsoh]

Checking the code, I've seen that the version is added in [1]. This is because, regardless of explicitly adding the "family" parameter, the class context is empty [2]. I've dumped what is in self.context in [1]:
ChainMap({}, {})

That means it will try to gather always IPv4 rules.

Example:

root@u20ovn:/var/log# ip netns exec $ns ip neigh
240.0.0.3 dev testca217cd5 lladdr fa:16:3e:1b:1e:fa STALE
240.0.0.2 dev testca217cd5 lladdr fa:16:3e:6d:e0:0f PERMANENT
fd00::3 dev testca217cd5 lladdr fa:16:3e:12:27:93 STALE
fd00::2 dev testca217cd5 lladdr fa:16:3e:39:88:48 PERMANENT

Oh. Fixing, will be ready tonight.

Should be fixed in the branch https://github.com/svinota/pyroute2/tree/svinota-neigh-dump-962

Pls take a look, and I merge it into master

[ralonsoh]

Tested [1] on the Neutron CI functional jobs and passing. Thanks for the patch.
