[Patch v3 0/6] Support VMBUS channels without monitoring enabled

[longli at linuxonhyperv.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. Becuase 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:
https://patchwork.dpdk.org/project/dpdk/patch/1742242184-19600-1-git-send-email-longli@linuxonhyperv.com/

Long Li (6):
  net/netvsc: introduce private data for storing vmbus device for
    secondary process
  net/netvsc: introduce get_vmbus_device to get the vmbus device
  bus/vmbus: store UIO fd for secondary process
  bus/vmbus: support channels without monitoring enabled
  bus/vmbus: add rte_vmbus_device to all functions accessing vmbus
  bus/vmbus: set event for channel without monitoring support

Change log:
v3: Add in the comment on the VMBUS API deprecation notice
