[dpdk-dev] [PATCH v3 1/8] net/ice: enable flow director engine

Yahui Cao yahui.cao at intel.com
Tue Sep 24 23:52:36 CEST 2019


From: Beilei Xing <beilei.xing at intel.com>

Enable flow director engine, including initialization and teardown.
 - Control VSI create and release.
 - Queue pair allocated, set up and release.
 - Programming packet create and release.
 - FDIR profile create and release.
