From bd4a41e6dee43b5b00876e37d42abffa298d63fe Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Wed, 16 Sep 2015 13:19:00 +0530 Subject: [PATCH] ath10k: fix ldpc param for fixed rate ldpc is not configured for fixed rates. This blocks auto rate vs fixed rate performance comparison. Since firmware is considering ldpc vdev param for fixed rate selection, it has to be configured to enable ldpc for fixed rates.
