Subject: [dpdk-dev] [PATCH v3 12/21] bus/fslmc: introduce support for hardware mempool object
Date: Sun, 9 Apr 2017 13:20:15 +0530	[thread overview]
Message-ID: <1491724224-6319-13-git-send-email-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <1491724224-6319-1-git-send-email-hemant.agrawal@nxp.com>

Each mempool instance is represented by a DPBP object
from the FSL-MC bus.
