FreeBSD drivers do not, as a general rule, announce separate version numbers (unless verbose boot is requested), and do identify the particular hardware device which is supported rather than the (generic) name of the product line. Consider the following juxtaposition, copied from the boot messages on this machine: usbus3: EHCI version 1.0 usbus3: <Intel 82801JI (ICH10) USB 2.0 controller USB-B> on ehci0 pcib5: <ACPI PCI-PCI bridge> irq 17 at device 28.0 on pci0 pci5: <ACPI PCI bus> on pcib5 igb0: <Intel(R) PRO/1000 Network Connection version - 2.2.5> port 0xdc00-0xdc1f mem 0xdf6e0000-0xdf6fffff,0xdf6c0000-0xdf6dffff,0xdf69c000-0xdf69ffff irq 16 at device 0.0 on pci5 >How-To-Repeat: Boot a machine with an Intel Gigabit Ethernet controller that is supported by the igb driver. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
