Subject: [dpdk-dev] [PATCH] common/cnxk: fix unaligned access to device memory
Date: Wed, 20 Apr 2022 12:08:25 +0530
Message-ID: <20220420063825.286183-1-psatheesh@marvell.com> (raw)

From: Satheesh Paul <psatheesh@marvell.com>

Use mbox_memcpy() instead of memcpy() to prevent unaligned access.

Fixes: 1f66919817e ("common/cnxk: improve MCAM entries management")
