Subject: [dpdk-dev] [PATCH v4] net/ice: support flow priority for DCF switch filter
Date: Thu, 15 Apr 2021 15:38:45 +0000 [thread overview]
Message-ID: <20210415153845.840636-1-yuying.zhang@intel.com> (raw)
In-Reply-To: <20210317070243.136145-1-yuying.zhang@intel.com>
Support rte flow priority attribute for DCF switch filter.
When a packet is matched by two rules, the behavior of it
is not defined. This patch supports flow priority to create
different recipes for this situation. Only priority 0 and 1
are supported and higher value denotes higher priority.
for example:
1. flow create 0 priority 0 ingress pattern eth / vlan tci
is 2 / vlan tci is 2 / end actions vf id 2 / end
2. flow create 0 priority 1 ingress pattern eth / vlan /
vlan / ipv4 dst is 192.168.0.1 / end actions vf id 1 / end
These two rules can be created at the same time in DCF switch
filter and priority of rule 2 is higher. Packet hits rule 2
when two conditions of rules are satisfied.
