This commit introduces a range of tests to the xsk testsuite for validating xsk statistics. A new test type called 'stats' is added. Within it there are four sub-tests. Each test configures a scenario which should trigger the given error statistic. The test passes if the statistic is successfully incremented. The four statistics for which tests have been created are: 1. rx dropped Increase the UMEM frame headroom to a value which results in insufficient space in the rx buffer for both the packet and the headroom. 2. tx invalid Set the 'len' field of tx descriptors to an invalid value (umem frame size + 1). 3. rx ring full Reduce the size of the RX ring to a fraction of the fill ring size. 4. fill queue empty Do not populate the fill queue and then try to receive pkts.
