Subject: [PATCH] skd: Change default interrupt mode to MSI-X
Git-commit: 744353b6951c3b7adbb9e4a1b2a529eabde61970
Patch-mainline: v4.14-rc1
References: bsc#1104967,FATE#325924
Since MSI support on some motherboards is unreliable, change the
default interrupt mode from MSI to MSI-X. This patch avoids that
the following message appears sporadially in the kernel logs of
my test setup:
do_IRQ: 3.193 No irq handler for vector
