From 99ad1cba313fc86797bca55d64e7c6c809098511 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Tue, 1 Mar 2016 13:16:11 +0100 Subject: [PATCH] ath10k: change htt tx desc/qcache peer limit config The number of HTT Tx descriptors and qcache peer limit aren't hw-specific. In fact they are firmware specific and should not be placed in hw_params. The QCA4019 limits were submitted with the peer flow control firmware only and to my understanding there's no non-peer-flow-ctrl QCA4019 firmware. However QCA99X0 is planned to run firmware supporting the feature as well. Therefore this patch enables QCA99X0 to use 2500 tx descriptors whenever possible instead of just 1424.
