This file implements some common helpers to consolidate differences in features and functionality between the various XDP samples and give them a consistent look, feel, and reporting capabilities. This commit only adds support for receive statistics, which does not rely on any tracepoint, but on the XDP program installed on the device by each XDP redirect sample. Some of the key features are: * A concise output format accompanied by helpful text explaining its fields. * An elaborate output format building upon the concise one, and folding out details in case of errors and staying out of view otherwise. * Printing driver names for devices redirecting packets. * Getting mac address for interface. * Printing summarized total statistics for the entire session. * Ability to dynamically switch between concise and verbose mode, using SIGQUIT (Ctrl + \). In later patches, the support will be extended for each tracepoint with its own custom output in concise and verbose mode.
