Thanks for the suggestion. We could make "accel" more general, then these two 
options (and other coming options) can be combined.

Currently "accel" only supports static configuration, which means user has to 
set its values before the associated VIF is allocated. I'd like to turn "accel" 
into be a dynamic option, so user can enable an accelerator for a VIF even when 
this VIF is running.

And the content of "accel" also could be in a multi-column format, rather than 
NIC name. For example, if "accel" could recognize 
"eth_name:feature:parameters", then user can pass flags to acceleration 
plug-in. This gives more flexibility.
