The idea behind this epic is two fold as following: 1. To achieve metric equivalence with what linux's ethtool provides. 2. To extend the functionality of the xstats API to enable the following options: ## the retrieval of aggregate stats upon request (Top level stats). ## the retrieval of the extended NIC stats. ## grouping of stats logically so they can be retrieved per logical grouping. ## the option to enable/disable the stats groups to retrieve similar to set private flags in ethtool.
