AMD Answer 000033663
When the DCMAC RX is operating in independent mode with the RX TSMAC in CL49 mode (i.e., processing 10GE/25GE clients), it incorrectly allows /E/, /S/; or /O-Res/,/S/ (which is either an error or a reserved O-code before an S character) to pass through the device.
This issue will not be fixed for the devices listed in the Errata Summary table.
