[dpdk-dev] [PATCH 2/6] net/i40e: support pipeline personalization profile

Beilei Xing beilei.xing at intel.com
Fri Mar 3 08:26:13 CET 2017


Add admin queue functions for Pipeline Personalization
Profile AQ commands defined in DCR 287:
 - Write Recipe Command buffer (Opcode: 0x0270)
 - Get Applied Profiles list (Opcode: 0x0271)
This patch will be moved to base driver in future.
