From a2b9b123ccac913e9f9b80337d687a2fe786a634 Mon Sep 17 00:00:00 2001 From: Mengyuan Lou Date: Tue, 7 Feb 2023 18:24:19 +0800 Subject: PCI: Add ACS quirk for Wangxun NICs Wangxun has verified there is no peer-to-peer between functions for the below selection of SFxxx, RP1000 and RP2000 NICS. They may be multi-function devices, but the hardware does not advertise ACS capability. Add an ACS quirk for these devices so the functions can be in independent IOMMU groups.
