Subject: [PATCH 0/3] PCI-e Max Payload Size configuration
Date: Wed, 29 Jul 2015 16:18:52 -0600	[thread overview]
Message-ID: <1438208335-19457-1-git-send-email-keith.busch@intel.com> (raw)

This patch series removes arch, driver, and hot-plug specific calls to
configure a PCI-e device's MPS setting. The device is instead configured
in the generic pci-core layer when the device is initially added, and
before it is bound to a driver.

The default policy is also changed from "do nothing" to update the
down stream port to match the upstream port if it is capable.
