Get RSS hash key, check that packets are directed to receive queues according to its value.

#. Check that RSS hash key can be obtained for IUT interface.

#. For every entry in RSS hash indirection table:
   
   * Find such address/port pairs on IUT and Tester that Toeplitz hash produces value mapped to the table entry.
   
   * Create a pair of connected sockets on IUT and Tester bound to these address/port pairs.
   
   * Send a few packets from Tester to IUT. Check that XDP hook reports that all the packets were processed by the Rx queue specified by the current indirection table entry.
