No, it doesn't seem to be necessary there - I haven't seen spontaneous
link-ups with the 88x3310 there. Even if we did, that would cause other
issues beyond a nusience l

Hi Russell
Is there something like this in the marvell10 driver?

Some SFP modules uses RX_LOS for link indication. In such cases link
will be always up, even without cable connected. RX_LOS changes will
trigger link_up()/link_down() upstream operations. Thus, check that SFP
link is operational before actual read link status.
