dpdk compress code - Acc

24 Nov 2022


      dpdk compress code&nbsp;is almost ready.
https://github.com/Linaro/dpdk/tree/next-11.24-compress.
The dpdk only support deflate,&nbsp;
We added some hack to use zlib, which will be removed when testing deflate
-&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;setup.alg_type = WD_ZLIB;
+&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;setup.alg_type = WD_DEFLATE;
-&nbsp; &nbsp; &nbsp; &nbsp;udev = wd_get_accel_dev("zlib");
+&nbsp; &nbsp; &nbsp; &nbsp;udev = wd_get_accel_dev("deflate");
