Mengyuan LouandGreg Kroah-Hartman 01923e3196 PCI: Add ACS quirk for Wangxun NICs
[ Upstream commit a2b9b123cc ]

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.
