I'm using a FS SFP-10GSR-85 transceiver connected to a Zyxel XS1930-10 switch: the switch shows the link as active, but FreeBSD never detects it on its end. I've tried setting dev.ax.{0,1}.link_workaround=1 but it doesn't have any effect.

IIRC, Franco reported that those cards work greatly with FS transceivers ?
