[PATCH] mwifiex: disable MSIx interrupt for 8997 chipset

[Amitkumar Karwar]

From: Shengzhen Li 

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.
