■ Byte 2 set to 0xFA.
■ Bytes 6-8 set to the length of the outbound data length (maximum transfer
length is 64K (0x10000)).
■ The mode will be set to 0x06 for the first and middle write buffers and
0x07 for the last.
Multiple upgrade firmware commands will generally be required to transfer
the entire program image from the host to the Interface Manager DRAM.
When the last data block is transferred (mode - 0x07), the Interface Manager
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 Interface Manager
will use the newly upgraded firmware. The previous firmware image is
discarded, and the controller continues to use the previous firmware image.
