From 9cd85b8b4c18c913ac1d63eb2b6d13e3230516a3 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Thu, 3 Dec 2020 13:44:42 +0000 Subject: [PATCH] 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.
