From bf942091678c51f53caa679d5fabebbe04a2ea66 Mon Sep 17 00:00:00 2001 From: Shengzhen Li Date: Tue, 21 Jun 2016 14:32:32 +0530 Subject: [PATCH] mwifiex: disable MSIx interrupt for 8997 chipset Sometimes MSIx interrupts are received out of order on multi-core system. This creates a problem when there is a race between data packet and SLEEP event from firmware. We will disable MSIx interrupt mode to solve the problem and go with MSI mode.
