this is the card that works in my tests:
em1@pci4:0:1: class=0x020000 card=0x34768086 chip=0x10968086 rev=0x01
hdr=0x00
vendor = 'Intel Corporation'
device = 'PRO/1000 EB Network Connection'
class = network
subclass = ethernet
and this is the one that do not work at gigabit speed:
em0@pci0:25:0: class=0x020000 card=0x2800103c chip=0x104a8086 rev=0x02
hdr=0x00
vendor = 'Intel Corporation'
device = '82566DM Gigabit Network Connection'
class = network
subclass = ethernet
