Unavoidable warning Session affinity for host reachable services needs kernel 5.7.0 #29736
Description
This warning pops up in our ginkgo CI:
Session affinity for host reachable services needs kernel 5.7.0 or newer to work properly when accessed from inside cluster: the same service endpoint will be selected from all network namespaces on the host.
There doesn't seem to be a way to avoid it when using session affinity with socket-level LB and Linux < v5.7.
