This allows to set NTF_EXT_MANAGED neighbor flag for managed neighbor
entries as per kernel commit 7482e3841d52 ("net, neigh: Add NTF_MANAGED
flag for managed neighbor entries"). The flag then indicates to the
kernel that the neighbor entry should be periodically probed for keeping
the entry in NUD_REACHABLE state iff possible.

When subscribing to neigh updates, the updates for all neigh
protocol families are received. However when listExisting is set,
the request is made with AF_UNSPEC family, this request does not
include AF_BRIDGE entries.
This patch add a second request for AF_BRIDGE entries.
Add test for existing AF_BRIDGE entry and make expectNeighUpdate
take a slice of expected updates
Creates a VXLAN interface for this test as its AF_BRIDGE entries
looks a lot like usual ones
Also add support for latest (2014+) neighbour attributes
NDA_MASTER was added back in 2014, it indicates whether a neigh
entry is linked to a master interface and index of this interface.
The other entries, namely NDA_LINK_NETNSID and NDA_SRC_VNI were
added later and will need extra handling.

The ip neighbour supports adding of peers statically using commands
where the lladdr is an IP address.
ip neighbor add 10.0.0.2 lladdr 203.0.113.6 dev tun8
This is used in the case of point-to-multipoint GRE to setup the
remote end point of the tunnel
Note that link-layer address and neighbor address are both IP addresses

Having object composition causes both client and library to
do potentially unecessary work to retrieve Link attributes
when only index is often sufficient.
