Hi all,

It seems that ix(4) is having problems with 1G BiDi sfp. I've tested
FS.COM 1G BiDi and they are working on mikrotik and some switches but on
OpenBSD I'm getting "status: no carrier" what ever I do.
I've tried:
advertise 1G without auto-negotiation and speed 1Gbps full duplex
advertise 1G with auto-negotiation
With those sfp's in OpenBSD I just can't disable auto-neg or configure
media to advertise 1G full-duplex.
With normal 1G sfp everything is working as expected on OpenBSD ix(4).

For link to be UP between network equipment with 1G BiDi i needed to
configure interfaces to advertise 1G without auto-negotiation and speed
1Gbps full duplex.

On other hand 10G BiDi is working as expected with auto negotiation,
means that I didn't need to configure anything for link to be up.
