      Description of problem:
      ethtool shows that combined now queue number is not equal to RX ring(s) number as x86 machine. is equal to 2 multiply RX ring(s)

      Version-Release number of selected component (if applicable):
      RHEL-9.2.0-20230301.7 ==> kernel-5.14.0-283.el9
      How reproducible:

      Steps to Reproduce:
      1. ethtool -L enP48p1s0f2 rx 0 tx 0 combined 8
      2. rx_now=COMBINED_NOW=`ethtool -l $TEST_IFACE | grep -w "Combined:" | tail -n 1 | awk '

      {print $2}

      '`
      3. rx_num=RING_NUM_NOW=`ethtool -x $TEST_IFACE | grep indirection | awk '

      {print $9}

      '`
      4. compare the $COMBINED_NOW and $RING_NUM_NOW

      Actual results:
      rx_now:8 should equal ring number:4 (Assert: '8' should equal '4')

      Expected results:
      rx_now equal to rx_num(ring_num)
