[c-nsp] C4510R and SFP interfaces

Asbjorn,
Sorry, had to go and read configuring interfaces in the explanation of configuring both ports you are correct, that the last slot falls back to only being able to support the 2 port gigabit module. So either use dual 10 gigabit, or the 4 gigabit uplinks, try not to require both or port density is lowered substantially.
