[GTPU] GTP-U support

[GinesGarcia]

Hi,
I'm trying set up a controller for GTP-U traffic but when running ryu-manager tunnel_gtpu.py I'm facing with the following error:
TunnelGTPU: Exception occurred during handler processing. Backtrace from offending handler [switch_features_handler] servicing event [EventOFPSwitchFeatures] follows. Traceback (most recent call last): File "/home/user/.local/lib/python2.7/site-packages/ryu/base/app_manager.py", line 290, in _event_loop handler(ev) File "/home/user/ryu-lagopus-ext/ryu/app/tunnel_gtpu.py", line 21, in switch_features_handler type_eth = (ofp.OFPHTN_ONF << 16) | ofp.OFPHTO_ETHERNET AttributeError: 'module' object has no attribute 'OFPHTN_ONF'

OFPHTN_ONF is defined in ofproto_v1_5.py but this controller is using ofproto_v1_3.py. If I force the controller to use ofproto_v1_5 instead of ofproto_v1_3, there are no compatible versions between them:
no compatible version found: switch versions set([4]) controller version 0x6, the negotiated version is 0x4, but no usable version found. If possi ble, set the switch to use one of OF version [6] on datapath ('127.0.0.1', 46702)

Any suggestion about how to handle this situation?

Regards,
Ginés.

Ok, I've finally solve the issue. Althought in the readme of https://github.com/lagopus/ryu-lagopus-ext the option of installing ryu via pip is proposed, you must to install it by using the setup.py file in order to have all the extended files correctly loaded.
