Is this a dupe / replacement of #196?

[cmluciano]

As discussed in SIG-Network meeting, the proposal has not been finalized according to the issues linked in the description. These issues should be addressed prior to an official milestone assignment.

[m1093782566]

I raised a PR about design proposa of supporting ipvs mode for kube-proxy, please check

kubernetes/community#692

[idvoretskyi]

@quinton-hoole @kubernetes/sig-network-feature-requests any updates for 1.8? Is this feature still on track for the release?

[idvoretskyi]

@quinton-hoole @kubernetes/sig-network-feature-requests can you confirm that this feature targets 1.8?

If yes, please, update the features tracking spreadsheet with the feature data, otherwise, let's remove this item from 1.8 milestone.

Thanks

@cmluciano @m1093782566 @Lion-Wei @quinton-hoole @kubernetes/sig-network-feature-requests --
We noticed that there was no response on this feature for the 1.11 Release Cycle, yet it's on the 1.11 Features tracking spreadsheet.

At this point, an exception would need to be filed for this to make it into the 1.11 milestone.
Please follow the process detailed here.

In addition, please update the line item for this feature on the Milestone risks sheet ASAP AND ping myself and @idvoretskyi, so we can assess the feature status or we will need to officially remove it from the milestone.

[justaugustus]

Exception was approved by @jberkus.
Just noting for record. This has been moved back to the primary sheet.

[justaugustus]

Closing this as the feature is GA in 1.11. Please feel free to reopen if there is still a need to track this.
