Subject: [dpdk-dev] [PATCH 11/25] net/bnxt: fix crash in VF rep queue selection
Date: Thu, 10 Sep 2020 18:55:49 -0700 [thread overview]
Message-ID: <20200911015603.88359-12-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20200911015603.88359-1-ajit.khaparde@broadcom.com>
From: Somnath Kotur <somnath.kotur@broadcom.com>
Instead of bounds checking against max possible rings while selecting
queue index for the VF rep, do it against the configured number of rings.
Fixes: 6dc83230b43b ("net/bnxt: support port representor data path")
