I can compile the master branch of netmap as they have ported the fix for the kernel modifications on Ubuntu; however, I can't get vpp to see any frames when using the pkt_gen program or running mtcp over netmap. I can't get this branch to compile on my system. I'm not sure if there are modifications in this branch that need to go into the main branch or vice versa. Any help would be appreciated. Thanks! I've looked into tldk but I want to be able to port my routing stack which is using the bsd socket apis which is why I'm looking at mtcp.
