[dpdk-dev] [PATCH] test: fix test_tlb_tx_burst

[Michal Jastrzebski <michalx.k.jastrzebski@intel.com>]

This patch fixes error in tlb_tx_burst function:
Distribution is not even.
A condition in TEST_ASSERT macro was changed,
as the previous one was random.
Also the time of generating packets can now be decreased.
