Comment 4 ffernand 2021-11-23 19:50:02 UTC 
Verified that all needed fixes are present in the latest OCP 4.7.z.
Marking this bz as MODIFIED.

The bug referenced from the kernel commit above is https://bugzilla.redhat.com/show_bug.cgi?id=1877128
which was Fixed-in-version kernel-4.18.0-254.el8.
Comment 5 ffernand 2021-11-23 21:26:12 UTC 
Ooops. No, that is not right.
While the kernel version is correct, openvswitch2.13-2.13.0-124.el8fdp.x86_64 does not include the fix needed:

* Thu Nov 18 2021 Open vSwitch CI <ovs-ci> - 2.13.0-139
- Merging upstream branch-2.13 [RH git: 37c2767bbd]
    Commit list:
    057a5b0708 ofproto-dpif-xlate: Fix check_pkt_larger incomplete translation.

Since OCP is using openvswitch2.13-2.13.0-124.el8fdp.x86_64, that needs to be updated to 139 still.

Re-opening the bz. Sorry about that.
Comment 7 ffernand 2021-11-23 22:35:15 UTC 
Nope; I was not wrong. :P

Since this bz does not depend on bug 1935663 , it is actually accurate to set this as MODIFIED.
openvswitch2.13-2.13.0-124.el8fdp.x86_64 includes all that is needed here.

In summary, please ignore comments 5 and 6 above. :)

4.7.30 is the first release with the necessary OVS (2.13-117) in the datapath.

https://openshift-release.apps.ci.l2s4.p1.openshiftapps.com/releasestream/4-stable/release/4.7.30
https://releases-rhcos-art.cloud.privileged.psi.redhat.com/diff.html?arch=x86_64&first_release=47.84.202109010857-0&first_stream=releases%2Frhcos-4.7&second_release=47.84.202109082139-0&second_stream=releases%2Frhcos-4.7

So this should actually already be fixed in latest 4.7.
