I would love to find out how they expect a customer to make the modification To "word 0x1A, and see if the 8th bit is 0 or 1, and to change to 0." I have in turn asked the ct for the lspci command on eth3, maybe the incorrect setting is upstream. Again, thank you.

Mismatches will cause hangs. Hi Todd, So far I had to know how to modify the maxpayload size, since BIOS have not entry to change this, so I had to use ethtool, now I need to get the offset of MaxPayload size in eeprom, I ever tried to find from Intel online document but failed, any idea?
