These all have PCI-E versions. Most should live in the config space
VPD.

01:00.0 Network controller: Mellanox Technologies MT27500 Family [ConnectX-3]
	Capabilities: [48] Vital Product Data
		Product Name: CX354A - ConnectX-3 QSFP
		Read-only fields:
			[PN] Part number: MCX354A-QCBT         
			[EC] Engineering changes: A1
			[SN] Serial number: MT1151X00841            
			[V0] Vendor specific: PCIe Gen3 x8    
			[RV] Reserved: checksum good, 0 byte(s) reserved

There is room for various vendor-specific things in the VPD if you
need.

I'm not sure, but I kinda remember there is even a PCI-E standard for
the temp sensor these days..
