Subject: [dpdk-dev] [PATCH 07/15] net/enic: enable limited PASSTHRU flow action
Date: Wed, 27 Feb 2019 23:03:09 -0800 [thread overview]
Message-ID: <20190228070317.17002-8-hyonkim@cisco.com> (raw)
In-Reply-To: <20190228070317.17002-1-hyonkim@cisco.com>
Some apps like VPP use PASSTHRU+MARK flow rules to offload packet
matching to the NIC. Just like MARK+RSS used by OVS-DPDK and others,
PASSTHRU+MARK is used to "mark and then receive normally". Recent VIC
adapters support such flow rules, so enable PASSTHRU for this limited
use case.
