[c-nsp] 10GE sanity check

[Tassos Chatzithomaoglou]

I had (accidentally) SFP 1000BaseLX/LH and 1000BaseZX talk to each other through SMF, regardless of 
their different wavelengths (!).

Although everything worked fine (passing traffic through) for some minutes, i replaced one of the 
SFPs in order to be sure i won't meet any problems in the future.
