[ofw] WIX installer questions concerning ConnectX driver install

[Fab Tillier]

Does MLX4_BUS ever create more than one child device?  Why not just function as an upper filter?  Why a bus driver?

Thanks!

MLX4_BUS is both a bus and a functional driver.
As the latter one it performs all the work against the HW.
It exports a high interface for anyone, wanting to use this
functionality.

It supports only ConnectX HCAs family, not the previous chips (,
supported by MTHCA).
The dev_ids and names one can see in mlx4_bus.inf file.

As the bus driver it creates one child device, supported by MLX4_HCA
driver.
MLX4_HCA is a virtual, HW-agnostic driver.
It's really just a thin shim, adjusting IBAL's low interface to the
MLX4_BUS's high one.
Wrt IBBUS, MLX4_HCA behaves exactly like MTHCA.
