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.
