I'm getting a panic during boot with this change: "unknown mac type d".
It occurs while the driver is attaching to:
em0@pci0:1:0:0: class=0x020000 card=0x7044103c chip=0x105e8086 rev=0x06 hdr=0x00
vendor = 'Intel Corporation'
device = '82571EB Gigabit Ethernet Controller'
class = network
subclass = ethernet
