app/test: fix bonding mode 5 Tx check
Test failed on verification if number of bytes transmitted on each slave is not less than 90% and greater than 110% of mean value of bytes transmitted thru one slave. This was verified on a real system but is difficult to achieve using virtualpmd. That's why for unit tests only, it is sufficient to verify that with high load (2 seconds transmission) all slaves are transmitting so the traffic is balanced. Fixes: 0c8396e6d786 ("bond: unit tests for mode 5") Signed-off-by: Michal Jastrzebski <michalx.k.jastrzebski@intel.com>
