[c-nsp] half duplex question

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
