Title:
QDF2400 PCI ports require ACS quirk
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Zesty:
Fix Released
Bug description:
Features of the QDF2400 PCI root ports are disabled because they do
not advertise an ACS capability. A quirk has been merged upstream that
re-enable these features on that platform:
commit 33be632b8443b6ac74aa293504f430604fb9abeb

PCI: Add ACS quirk for Qualcomm QDF2400 and QDF2432
The Qualcomm QDF2xxx root ports don't advertise an ACS capability, but
they
do provide ACS-like features to disable peer transactions and validate bus
numbers in requests.
To be specific:
* Hardware supports source validation but it will report the issue as
Completer Abort instead of ACS Violation.
* Hardware doesn't support peer-to-peer and each root port is a root
complex with unique segment numbers.
* It is not possible for one root port to pass traffic to the other root
port. All PCIe transactions are terminated inside the root port.
Add an ACS quirk for the QDF2400 and QDF2432 products.
