From dc3632a1adf51d34dcaf708a4f686d9ce29d53b3 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Mon, 30 Mar 2015 14:14:28 +0300 Subject: [PATCH] ath10k: fix HTT op backwards compatibility for QCA6174 Commit 8348db298496 ("ath10k: add ATH10K_FW_IE_HTT_OP_VERSION") broke QCA6174 receive side as the HTT ids from ATH10K_FW_HTT_OP_VERSION_MAIN don't have HTT_TLV_T2H_MSG_TYPE_RX_IN_ORD_PADDR_IND set. Fix this by adding a backwards compatibility code which sets HTT op version if it's not set by the firmware image.
