Mam IBM 3500 a na tento stroj jsem hodil 7.1 Release (x386). Sitovky jsou podle pciconf:

bge0@pci0:26:0:0:       class=0x020000 card=0x02c61014 chip=0x165914e4 rev=0x21 hdr=0x00
    vendor     = BroadcomCorporation
    device     = 'BCM5721 NetXtreme Gigabit Ethernet PCI Express'
    class      = network
    subclass   = ethernet
bge1@pci0:27:0:0:       class=0x020000 card=0x02c61014 chip=0x165914e4 rev=0x21 hdr=0x00
    vendor     = BroadcomCorporation
    device     = 'BCM5721 NetXtreme Gigabit Ethernet PCI Express'
    class      = network
    subclass   = ethernet

dmesg:
bge0: BroadcomNetXtreme Gigabit Ethernet Controller, ASIC rev. 0x4201> mem 0xc8400000-0xc840ffff irq 16 at device 0.0 on pci26

Problem je v tom, ze pouze jedna sitovka - bge0 jede na 1000full-duplex, kdezto bge1 autodetekuje 100full-duplex a zadnym zpusobem si nenecha vnutit 1000. I kdyz interface natvrdo ohnu k 1000 tak stejne jede 100. Stejne tak i konkretni port na gigovem switchi jsem prepnul z negotation na pozadovany mod a zadna zmena. Kabelaz je v poradku, switchem to neni, vadnej port sitovky to taky neni, protoze kdyz dam nejaky live distro linuxu tak me to v pohode obe sitovky detekuje a pres negotation dostanu full1000. Takze chyba je jednoznacne v 7.1 fbsd respektive v bge driveru. Je to ponekud zvlastni, protoze se jedna o pomerne uz zabehlej chipset viz. BCM5721 coz neni zadna horka novinka a presto takovato banalani vec nefunguje. Co s tim? Rad bych pouzil obe sitovky a pres lagg je oprel oproti LACP trunku na switchi. Takhle mam ale stera.

Nastaveni parametru rozhrani natvrdo:
