Hi All,
I want to enable GTP-U in OpenVswitch. I have implemented the code for the
GTP-U in ovs and submitted the same on ovs-dev.
As currently, GTP-U support is not available in upstream linux kernel, so to
create a GTP port in ovs we have to load the openvswitch kernel
module to linux kernel.
I have received some review comments stating that first I have to implement the
code for GTP-U in upstream linux kernel in netdev net-next
tree then it can be incorporated into ovs.
I want to know the process of how to implement and get the code for GTP-U into
upstream linux kernel.
If anybody is working on the same how can I help them to get it in into the
upstream linux kernel quickly.
I'm a bit out of touch with OVS, so my idea on how this should work might be
wrong.
As far as I understand OVS, the way forward would be to use the lwtunnel
infrastructure to enable OVS to use a kernel GTP module.
Our current OVS module ([1], [2]) is not (yet) using lwtunnel, but we do plan
on switching to that.
So far, we have been coordinating the GTP kernel module development on the OpenBSC ML [3]. The goal is to upstream it as soon as all the
basics are covered (smallish netlink API changes, final touches on IPv6 and maybe lwtunnel).
On the OVS side, someone would then need to implement the necessary ops to
handle GTP lwtunnel integration.
