Comment 0 for bug 2056718

Intro:
======
When hit a kernel warning when using openvswitch kernel module. Digging into the source code, we found it's due to the code snippet
        if (WARN_ON(i.cmd >= family->resv_start_op &&
                   (i.doit.validate || i.dumpit.validate)))
                 return -EINVAL;

in the gene_validate_ops() in net/netlink/genetlink.c, introduced in
108880a07bab genetlink: add iterator for walking family ops
from buglink

How to fix:
===========
We need to cherry-pick the missing patch

    net: openvswitch: add missing .resv_start_op

    I missed one of the families in OvS when annotating .resv_start_op.
    This triggers the warning added in commit ce48ebdd5651 ("genetlink:
    limit the use of validation workarounds to old ops").
