Subject: [dpdk-dev] [PATCH v3 04/14] net/bnxt: fix to avoid accumulation of flow counters
Date: Sat, 18 Jul 2020 00:25:05 -0700 [thread overview]
Message-ID: <20200718072515.62969-5-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20200718072515.62969-1-ajit.khaparde@broadcom.com>
From: Somnath Kotur <somnath.kotur@broadcom.com>
OVS-DPDK is accumulating the flow counters that are returned as part
of the flow_query API and it is being issued at least 3 times every second.
So there is no need to accumulate the counts internally in the driver.
Fixes: 306c2d28e247 ("net/bnxt: add support for flow query with action_type COUNT")
