The correct serial number presentation should be the same
as the one on the sticker of the HBA card.
The PCIe Device Serial Number Capability Structure contains
+-------------------------------------+
| PCIe Enhanced Capability Header | 0x00
+-------------------------------------+
31:0 | Serial Number Register (Lower Dword)| 0x04
+-------------------------------------+
63:32 | Serial Number Register (Upper Dword)| 0x08
+-------------------------------------+
The Serial Number register shown above is a 64-bit field
that contains the IEEE defined 64-bit Extended Unique
Identifier (EUI-64):
+-----+-------------------------+
|Byte | |
|Order| Description |
+-----+-------------------------+ low
| 0 | Company ID |
| 1 | |
| 2 | |
+-----+-------------------------+
| 3 | MAC Label (0xFFFF) |
| 4 | |
+-----+-------------------------+
| 5 | Extension Identifier |
| 6 | |
| 7 | |
+-----+-------------------------+ high
The 48-bit serial number shown on the HBA card is constructed from
47 24 23 0
+----------------------+----------------------+
high | Extension Identifier | Company ID | low
+----------------------+----------------------+
