Subject: [dpdk-dev] [PATCH v1 3/6] raw/ioat: add explicit padding to descriptor struct
Date: Thu, 18 Mar 2021 18:20:39 +0000	[thread overview]
Message-ID: <20210318182042.43658-4-bruce.richardson@intel.com> (raw)
In-Reply-To: <20210318182042.43658-1-bruce.richardson@intel.com>

Add an explicit padding field to the end of the descriptor structure so
that when the batch descriptor is defined on the stack for perform-ops, the
unused space is all zeroed appropriately.
