Subject: [dpdk-dev] [PATCH v2 08/13] baseband/fpga_5gnr_fec: add HW error capture
Date: Sun, 29 Mar 2020 17:02:55 -0700
Message-ID: <1585526580-113508-9-git-send-email-nicolas.chautru@intel.com> (raw)
In-Reply-To: <1585526580-113508-1-git-send-email-nicolas.chautru@intel.com>

Adding HW specific parsing of error report for
negative scenarios. Not hit through unit test.
