Subject: [dpdk-dev] [PATCH v3 01/23] bus/fslmc: fix to use ci value for qbman 5.0
Date: Wed, 24 Feb 2021 18:12:49 +0530
Message-ID: <20210224124311.29799-2-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <20210224124311.29799-1-hemant.agrawal@nxp.com>

From: Youri Querry <youri.querry_1@nxp.com>

Random portal hangs observed on device with QBMAN 5.0

This fixes few random packet hang issues in event mode.
Few things fixed it.
1. Generally, pi == ci, no need for extra checks.
2. The proper initializations in init with ci

Fixes: 1b49352f41be ("bus/fslmc: rename portal pi index to consumer index")
