You can try to get windows register setting by

Pci config space register 0x80/0x84
For example, to read register 0x1480
Pci configure write 0x1480 to [0x80] (32bit)
Pci configure read [0x84]

Only 32 bit read/write is allowed.

Thanks

Are you sure the NIC is ok for windows driver ? it might be an HW bug, if it’s

the case, your checksum verificated by protocol is a workaround.

Yes, the NIC is ok in Windows.
