Is it?  If I recall correctly, TSO was in place well before all drivers 
were using NAPI.  And NAPI was being proposed independent of TSO. TSO is 
there to save CPU cycles on the transmit side.  "On the wire" what it 
sends is to be identical to what a host with greater CPU performance 
could accomplish.
