Subject: [dpdk-dev] [PATCH v2 02/20] bus/dpaa: fix statistics reading
Date: Thu, 11 Feb 2021 19:46:02 +0530
Message-ID: <20210211141620.12482-3-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <20210211141620.12482-1-hemant.agrawal@nxp.com>

From: Nipun Gupta <nipun.gupta@nxp.com>

Reading of word un-aligned values after reading word aligned
values lead to corrution of memory, such that older value.
This patch make changes such that word alignedaccess is made,
before making an un-aligned access
