PCI: Add ACS quirks for Cavium multi-function devices
Some Cavium endpoints are implemented as multi-function devices without ACS capability, but they actually don't support peer-to-peer transactions. Add ACS quirks to declare DMA isolation for the following devices: - BGX device found on Octeon-TX (8xxx) - CGX device found on Octeon-TX2 (9xxx) - RPM device found on Octeon-TX3 (10xxx) Link: https://lore.kernel.org/r/20210810122425.1115156-1-george.cherian@marvell.com Signed-off-by: George Cherian <george.cherian@marvell.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
