In case no Tx disable pin is available the SFP modules will always be

not have its tx_disable pin wired or available.

Is this something that was done in a possibly earlier revision of a
given board design and which was finally fixed? Nothing wrong with the
patch, but this seems like a pretty serious board design mistake, that
needs to be addressed.
