Subject: [PATCH] PCI: Mark Intel XXV710 NIC INTx masking as broken
Git-commit: d40b7fd2cbcbeeff36e52aef2aa44e03a2ab7345
Patch-mainline: v4.13-rc1
References: bsc#1120058
Just like the other XL710 and X710 variants, the XXV710 device IDs appear
to have the same hardware bug, the status register doesn't report pending
interrupts resulting in "irq xx: nobody cared..." errors from the spurious
interrupt handler when we try to use it with device assignment.
