Converged Network Adapters, NPARs and VLAN tagging

Sorry if this is slightly off-topic here but I have a question on
NPARs/CNAs/Blade IO modules.

If you divide up the CNA into 4 NPARs can you VLAN tag at both the
firmware level (pre-OS) and/or OS level? Do the blade IO modules allow
double tagging on the internal ports?

Generally what is the best practice: to VLAN tag at the CNA firmware
or at the OS level?

Thanks
