Title:
  xgene-pcie: Fix max payload size and phantom function configuration

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” source package in Trusty:
  Fix Committed
Status in “linux” source package in Utopic:
  Fix Committed

Bug description:
  [Impact]
  Systems under stress may encounter malformed TLP issues, which can result in networking "dropping out" after multiple hours.
  [Test Case]
  lspci -vvv output will show a "MalfTLP+" in the Capabilities: [154 v2] Advanced Error Reporting section.
  [Regression Risk]
  Restricted to the xgene-pcie driver, so regression risk is restricted to the X-Gene platform, which has had many hours of testing with the proposed fix.
