For example (from various machines): fxp0@pci2:12:0: class=0x020000 card=0x00018086 chip=0x12298086 rev=0x08 fxp2@pci0:3:0: class=0x020000 card=0x34108086 chip=0x12298086 rev=0x0d fxp0@pci2:4:0: class=0x020000 card=0x10f08086 chip=0x12298086 rev=0x05 fxp0@pci0:12:0: class=0x020000 card=0x30008086 chip=0x12298086 rev=0x08 Card is the mounting (NIC, MB, etc...). The Intel driver have a fairly complete list of models/makers. rev=0x08 for a chip 0x12298086 is a 82559 stepping A0 rev=0x0d for the same chip is a 82550 Stepping C. rev=0x05 is a 82558 B0 stepping. As a rule of thumb, roughly 4 revs are reserved per chips: 0-3 : 82557 4-7 : 82558 8-11: 82559 12-..: 82550 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
