We support the kernels listed in our releases FAQ for a particular OVS version:
http://docs.openvswitch.org/en/latest/faq/releases/
2.11 does indicate that kernel 4.15 should be supported. It looks like OVS
compiles fine against 4.15.0-58, but something changed in 4.15.0-60. I went
ahead and pulled the patches you recommended and pushed them to branch-2.11.
Thanks for figuring it out.
I'll skip the 2.11.2 release announcement and just jump to 2.11.3.
Thanks again!
