You mask the drv_flags, do you plan on merging those flags
in the demuxing drivers above? It seems LSC | RMV | PROBE_AGAIN
is not used afterward, seems missing.

Using an rte_pci_driver instead of an rte_driver as core object
for you driver would allow managing this by the way.

After reading it more, I think bus_pci_mlx5 would work better.
From the more general to the specific (bus >> pci >> mlx5 demux).

Yes. but how would mlx5_pci bus will process the drv_flags passed by the class drivers such a vdpa/net?

LSC and RMV are used within rte_eth_copy_pci_info(), which is called by
each individual netdevice PCI probe callback, after creating an ethdev.

PROBE_AGAIN is used by the PCI bus to determine whether to throw -EEXIST
when attempting to probe again a device.

They will all access it through the demux PCI device -> PCI driver,
which will be in that case your demux driver. It needs to have a correct
value that will not mask underlying device capability or behavior.

Binary-AND between classes is bare-minimum, and would probably not work
for LSC. Some finer-grained control could be used to work well with
other layers.
