Previously stats were gotten by RTM_GETLINK which returns 32 bits based statistics. It supports only one type of stats. Lately, a new method to get stats was added - RTM_GETSTATS. It supports ability to choose stats type. The basic stats were changed from 32 bits based to 64 bits based.
This patchset adds ifstat the ability to get extended stats by this method. Its adds two types of extended stats: 64bits - the same as the "normal" stats but get the stats from the cpu in 64 bits based struct. SW - for packets that hit cpu. --- v1->v2: - change from using RTM_GETSTATS always to using it only for extended stats. - Add 64bits extended stats type.
