The approach is nice and clean, but the changes to rte_eth_dev_info are 
an ABI break.

One alternative is to add a new function (and associated driver function 
pointers) to fetch the version string, but my feeling is if one is to go 
down that road, they may as well generalise it into a driver info 
querying mini-API.
