Note Multiple Upgrade Firmware commands will generally be required to transfer the entire program image from the host to the bridge DRAM. When the last data block is transferred (mode = 0x07) the bridge terminates data transfer and performs a CRC checksum on data received. It is required that the FC initiator sends sequentially from the beginning of the firmware image to the end. No out of sequence Write Buffers are allowed. If the CRC test is successful, the Controller will reboot. The bridge will use the newly upgraded firmware. The previous firmware image is discarded. If the CRC test fails, the image transferred to DRAM is discarded, and the controller continues to use the previous firmware image. Multi-frame sequences are allowed. Transfer Length for each write must be less than or equal to 64KB (65536 bytes). It is required that the Parameter list length be the same as the FCP_DL field in the FCP_CMND IU. 210 In-Band Management Appendix B
