Subject: [dpdk-dev] [PATCH v2 03/15] baseband/turbo_sw: fix the exposed LLR decimals assumption
Date: Wed,  4 Mar 2020 10:22:20 -0800
Message-ID: <1583346152-10186-4-git-send-email-nicolas.chautru@intel.com> (raw)
In-Reply-To: <1583346152-10186-1-git-send-email-nicolas.chautru@intel.com>

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

The actual LLR representation was incorrectly assumed to be 2
instead of 4. This would impact wireless performance but is not
critical to be back ported on LTS branches.

Fixes: c769c711757a ("baseband/turbo_sw: extend for 5G")
