> Subject: [EXTERNAL] [Patch v7 0/4] Support VMBUS channels without
> monitoring enabled
>
> From: Long Li <lon...@microsoft.com>
>
> Hyperv may expose VMBUS channels without monitoring enabled. In this
> case, it programs almost all the data traffic to VF.
>
> This patchset enabled vmbus/netvsc to use channels without monitoring
> enabled.
>
> This needs to change the APIs exposed by drivers/bus/vmbus. Because those
> APIs are used only by NetVSC PMD and not feasible for use by a DPDK
> application, all VMBUS APIs are set to deprecate in upcoming 25.11 release.
>
> The notice for deprecation is accepted in the following patch:
