<p class="MsoNormal">Hi, DTS developers/users,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With DPDK development rapidly, more and more test suites were developed in DTS. (150+ test suites and 3k+ test cases in DTS). Meanwhile, paralleling execution tests for NICs/crypto/other device on same DUT become important for reducing
execution time for covering all test cases. So we plan to enhance the DTS, for<o:p></o:p></p>

<p class="MsoNormal">Generic EAL options generator for DPDK based application<o:p></o:p></p>
<p class="MsoNormal"> * Generate EAL options for DPDK app, and consider the assigned hardware resource for test, instead of whole DUT<o:p></o:p></p>
<p class="MsoNormal"> * Test suite can overwrite the options, in restricted range<o:p></o:p></p>
<p class="MsoNormal"> * Define hardware resource in crb.cfg, port.cfg and pktgen.cfg<o:p></o:p></p>
