Public bug reported:

[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.
