It's up to you but you could just leave nictype set to the default (as
initialised by libxl_device_nic_init and let the library do the right
thing based on the guest type.

This bit would remain valid whether or not you did the above.

Ultimately up to you whether you want to precisely control things or
just follow the defaults.
