Not sure if it's worth fixing, you may turn these warnings off with -Wno-attributes.

Could you install a matching kernel headers package? At the same time, I agree that we should improve the check in OVS and avoid failures when rtnetlink header exists in the system, but doesn't have this structure defined. > I've attached the full build log. In the log you also have errors pointing to missing OpenSSL functions. You'll need to upgrade your version of OpenSSL to at least 1.1.1, as older versions are no longer supported since OVS 3.5. Alternatively you may disable SSL/TLS support with --disable-ssl configuration knob.
