From 0fd01ebca05f72d33d630a868e9f6617503f6c08 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Thu, 3 Dec 2020 13:44:42 +0000 Subject: [PATCH 337/634] PCI: brcmstb: Advertise MSI-X support Although the BRCMSTB PCIe interface doesn't technically support the MSI-X spec, in practise it seems to work provided no more than 32 MSI-Xs are required. Add the required flag to the driver to allow experimentation with devices that demand MSI-X support.
