[dpdk-dev] [RFC] examples/ethtool: enhance ethtool app in i40e

[Qiming Yang <qiming.yang@intel.com>]

Now, run the example/ethtool, the drvinfo can not show the fireware
information. From customer point of view, it should be better if we
can have the same as kernel version ethtool show the bus-info and
firmware-version. We need to add a variable in struct rte_eth_dev_info
to get the fw version.
I’m interested in:
a) this approach is appropriate?
b) would prefer a change of the API?
