In addition, the number of TxGFP instruction does not match the firmware image size, so I guess something was wrong when Adaptec generated the TxGFP firmware from their DDK. According to datasheet, normally, the first GFP instruction would be opcode C, WaitForStartOfFrame, to synchronize checksumming with incoming frame. But the first instruction in TxGFP firmware was opcode 1, BrToImmIfTrue, so it could not process checksum correctly, I guess. Checking for RxGFP firmware also indicates the first instruction should be opcode C. Since the number of instructions in TxGFP firmware lacks exactly one instruction, I prepended the opcode C to TxGFP firmware image. With this change, the resulting image size perfectly matches with the nummber of instructions and Tx checksum offload seems to work without problems. |
