It will be pushed if I get no objections before 11/27/20. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Queued patches are on a temporary branch at: https://github.com/kevintraynor/dpdk-stable-queue This queued commit can be viewed at: https://github.com/kevintraynor/dpdk-stable-queue/commit/d83d4c863a8dc1c54c5da75a2709717d86c16309 Thanks.

While each packet that is sent to a representor will be received by the VF. This is very useful in case of SRIOV mode, where the first packet that is sent by the VF will be received by the DPDK application which will decide if this flow should be offloaded to the E-Switch. Representor shares interrupts handler with host PF over the PCI address. Therefore, after PF completes its interrupts handler initialization, no additional actions required for representor.
