Subject: [dpdk-dev] [PATCH v2 01/13] bbdev: add capability flag for filler bits inclusion in HARQ
Date: Sun, 29 Mar 2020 17:02:48 -0700
Message-ID: <1585526580-113508-2-git-send-email-nicolas.chautru@intel.com> (raw)
In-Reply-To: <1585526580-113508-1-git-send-email-nicolas.chautru@intel.com>

From: Nic Chautru <nicolas.chautru@intel.com>

Adding capability flag for device variants when HARQ buffer
may or may not include the filler bits.
Minor cosmetic changes in same file.
