[nsp] IPv6 Layer-3 capable switch recommendation

[Tim Stevenson]

Sup2 does IPv6 in the v6 software CEF switched path with current 12.2SX 
based code; it is not process switched.

You can expect >200Kpps (with 100% CPU @ 64 byte packets). For realistic 
packet sizes, eg 1Kbyte packets, >100Kpps at 70% CPU.

YMMV.
