From: Kirill Rybalchenko Date: Tue, 24 Oct 2017 14:08:13 +0000 (+0100) Subject: net/i40e: add support for packet template to flow director X-Git-Tag: spdx-start~1128 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=66c78f4799ff5021b749534cc35da2ae20f92397;p=dpdk.git net/i40e: add support for packet template to flow director For complex packets use raw flow type with pre-constructed packet buffer instead of creating a packet internally in PMD.
