Yes other info name are usually capitalized.
All of them appear in lstopo verbose, but not in the default output
(because we don't want a huge text output by default and it's hard to
decide which ones matter).
I just wrote a patch that adds Port=1/2 to all Net devices:
PCI 15b3:673c (P#28672 busid=0000:07:00.0 class=0c06(IB) PCIVendor="Mellanox Technologies" PCIDevice="MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE]") "Mellanox Technologies MT26428 [ConnectX VPI PCIe 2.0 5GT/s - IB QDR / 10GigE]"
Net L#6 (Address=80:34:00:48:fe:80:00:00:00:00:00:01:00:02:c9:03:00:0b:53:49 Port=1) "ib0"
Net L#7 (Address=80:34:00:49:fe:80:00:00:00:00:00:00:00:02:c9:03:00:0b:53:4a Port=2) "ib1"
OpenFabrics L#8 "mlx4_0"
PCI 14c1:0008 (P#24576 busid=0000:06:00.0 class=0200(Ether) PCIVendor="MYRICOM Inc." PCIDevice="Myri-10G Dual-Protocol NIC") "MYRICOM Inc. Myri-10G Dual-Protocol NIC"
Net L#5 (Address=00:60:dd:47:c3:cd Port=1) "myri0"

Net L#0 (Address=b8:ac:6f:83:df:80 Port=1) "eth0"
PCI 14e4:1639 (P#4097 busid=0000:01:00.1 class=0200(Ether) PCIVendor="Broadcom Corporation" PCIDevice="NetXtreme II BCM5709 Gigabit Ethernet") "Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet"
Net L#1 (Address=b8:ac:6f:83:df:82 Port=1) "eth1"
By the way, do you want Port numbers to start at 0 or 1?
