If so what model #?wow that went realy over my head but let me try to explain wat i know , the hardware itsels functions the only interface that links that previusly work was igb2 , i put igb1 and igb2 as a pcie with 2 nics , but after updating and putting some plugins now th nics show all link when i put ethernet cable on there really dont know why but better for me i think.
There's a SMBus controller in pciconf, this could be how bypass is controlled once OS boots.
dmesg|grep -Ei "bypass|watchdog"
The relays could be commanded from OS via gpio, this would need investigating as I suspect there's nothing in OPNsense distro supporting this bypass out-of-the-box.
2nd, online info suggests the bios should have a util for setting the default state of the bypass.
Was the bypass even tested with the OS running? Two laptops with IP in same /24, two x-over cables, laptops each connect to the matching bridge ports (looks like AAA over BBB), so any vertical pair. Can the laptops ping each other? If no x-over cables then two small switches, or one switch that can be managed to have two vlans, A-port and laptop-A on one vlanID, B-port and laptop-B on the other vlanID.
Depending on what the bios has available, it may be difficult to control the bypass on freeBSD. Can probably find some source code to compile, or even an existing klm, so more digging is needed.
