Running 8.0R I've noticed the same problem with this card (0x107c8086).
       Duplex and speed are manually set at full/1000.


em0 at 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
