Ben:
I have a driver for 2.4.x that works with our SFP/XFPs. We also have a
bunch of other 'stuff'
hanging off of muxes. I haven't given it a go on 2.6, but I have it
compiled and it doesn't complain on
startup.
Not sure if I should send it here, as it won't be in patch form...
Lemme know if you want a look-see,
Travis
