+# PCI Card Enumeration Script

+# This is what lspci output looks like:
+# [empty line]
+# Slot:	01:00.0
+# Class:	RAID bus controller
+# Vendor:	LSI Logic / Symbios Logic
+# Device:	MegaRAID SAS-3 3108 [Invader]
+# SVendor:	IBM
+# SDevice:	Device 0454
+# PhySlot:	4
+# Rev:	02
+# NUMANode:	0
+# [empty line]
+# [another section]
+
+# Expected output:
+# pci_device_0 => NetXtreme BCM5719 Gigabit Ethernet PCIe
+# pci_device_1 => SFC9220 10/40G Ethernet Controller
+# pci_device_2 => SFC9220 10/40G Ethernet Controller
+# pci_device_4 => MegaRAID SAS-3 3108 [Invader]
