From 6419fdbb6f90e147690f8833cba59d289d613da5 Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Wed, 11 Nov 2015 17:31:26 +0530 Subject: [PATCH] ath10k: poll HTT send completion when CE 5 is unused commit a70587b3389a ("ath10k: configure copy engine 5 for HTT messages") moved send completion polling under HTT Rx (CE 5) service routine. For QCA6174 based devices copy engine 1 (CE 1) is used for HTT Rx instead of CE 5. So send completion never be called. This is causing "failed to transmit packet, dropping: -105" errors. Fix this by processing send completion from CE 1 service routine instead of CE 5.
