Running 8.0R I've noticed the same problem with this card (0x107c8086).
Duplex and speed are manually set at full/1000.
em0@pci0:3:3:0: class=0x020000 card=0x13768086 chip=0x107c8086 rev=0x05
hdr=0x00
vendor = 'Intel Corporation'
device = 'Gigabit Ethernet Controller (Copper) rev 5 (82541PI)'
class = network
subclass = ethernet
