[dpdk-dev] [PATCH v3 3/4] net/bond: dedicated hw queues for LACP control traffic
Declan Doherty
declan.doherty at intel.com
Tue Jul 4 18:46:26 CEST 2017
From: Tomasz Kulasek <tomaszx.kulasek at intel.com>
Add support for hardware flow classification of LACP control plane
traffic to be redirect to a dedicated receive queue on each slave which
is not visible to application. Also enables a dedicate transmit queue
for LACP traffic which allows complete decoupling of control and data
paths.
This only applies to bonding devices running in mode 4
(link-aggegration-802.3ad).
Introduce two new APIs to support enable/disabled of dedicated
queues.
- rte_eth_bond_8023ad_dedicated_queues_enable
- rte_eth_bond_8023ad_dedicated_queues_disable
rte_eth_bond_8023ad_dedicated_queues_enable must be called before
bonding port is configured or started to reserved and configure the
dedicated queuesh.
When this option is enabled all slaves must support flow filtering
by ethernet type and support one additional tx and rx queue on
each slave.
