Header Log, Offset 0x1C
The header log register captures the header for the transaction that generated an error.
This register is 16 bytes.
Device Serial Number Capability
The PCIe device serial number capability is an optional extended capability that can be
implemented by any PCIe device. The device serial number is a read-only 64-bit value
that is unique for a given PCIe device.
All multi-function devices that implement this capability must implement it for function
0; other functions that implement this capability must return the same device serial
number value as that reported by function 0. The 82574L is not a multi-function device.

Capability Version
PCIe Extended Capability ID
This field is a PCI-SIG defined ID number that indicates the nature and format of
the extended capability.
Extended Capability ID for the Device Serial Number Capability is 0x0003.
Capability Version
This field is a PCI-SIG defined version number that indicates the version of the
capability structure present.
Must be 0x1 for this version of the specification.
Next Capability Offset
This field contains the offset to the next PCIe capability structure or 0x000 if no
other items exist in the linked list of capabilities.
For extended capabilities implemented in device configuration space, this offset is
relative to the beginning of PCI compatible configuration space and thus must
always be either 0x000 (for terminating list of capabilities) or greater than 0x0FF.
