Hello,

================

MaxPayload 512 bytes, MaxReadReq 512 bytes

...

AERCap: First Error Pointer: 00, ECRCGenCap+ ECRCGenEn- ECRCChkCap+ ECRCChkEn-

Hello,

I've solved this problem.

I can change these values using "setpci" command in my Linux system and also I can find the register on Intel E810-C datasheet.

Thanks!
