Subject: [dpdk-dev] [PATCH v2 17/25] net/bnxt: check and set initial counter ID
Date: Tue, 15 Sep 2020 21:28:43 -0700
Message-ID: <20200916042851.32914-18-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20200916042851.32914-1-ajit.khaparde@broadcom.com>

From: Somnath Kotur <somnath.kotur@broadcom.com>

Instead of relying on value of Flow counter ID to determine validity
have an explicit boolean flag for the same to check and set.

Fixes: 306c2d28e247 ("net/bnxt: support count action in flow query")
Fixes: 9cf9c8385df7 ("net/bnxt: add ULP flow counter manager")
