[c-nsp] half duplex question

[Scott Granados]

This gives me flashbacks to the old GlobalCentre network.  Many connections 
handed off to colocation customers were half duplex.  It was squirrely.

The issue you will have is that 10Mb/s Half duplex will only get about 3 to 
4 Mb/s worth of traffic.  This is because you will start to see collisions 
on the line.

Some is void of clue at the provider side.   Proper traffic policies should 
limit your bandwidth.  Not playing dumb duplex games.

I would strongly recommend that full-duplex be enabled on both ends
