[c-nsp] LX vs. LH GBICs

[Matt Stevens]

A little follow-up. We got our link working with a GBIC that was 
reporting LH on the Catalyst side.

I haven't been able to get any info out of the telco, like show 
interface capabilities. So I'm really confused as to what the difference is.

It feels like there was a change in the Cisco part at some point, and 
our equipment's working with one revision but not the other.

If anyone can shed some light on the difference between the GBICs 
reporting LX and those that report LH - I'd love to solve this mystery 
for future reference.
