Add port tunnels support according to OFConfig specification.
Signed-off-by: Raman Budny <raman_bu...@epam.com>
---
Port tunnel support in of_config library seems to be supported
in not full manner. There are four kind of port tunnels listed in
OFConfig specification (v1.1.1, p. 47):
- OFPortBaseTunnelType,
- OFPortIPGRETunnelType,
- OFPortVXLANTunnelType,
- OFPortNVGRETunnelType,
but currently there is no way to get/modify parameters of these tunnels in
of_config library. This patch should add required classes and link them
to OFPortType.
Unfortunately,
1) last three classes should inherit elements from
OFPortBaseTunnelType, but I haven't found simple way to implement it
without deep code rewriting (because of _ELEMENTS is class variable).
2) I haven't found suitable way to represent the relation of
mutual exclusion between different tunnel type objects
(i. e. port object should refer to only one tunnel object of
specific type).
I will be glad to receive your advices, how to implement these features,
and ready to improve this patch according to them.
