Subject: mwifiex: disable MSIx interrupt for 8997 chipset
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bf942091678c51f53caa679d5fabebbe04a2ea66;p=linux-beck.git

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.
