[c-nsp] Switch support for IPv6 policing

That is odd I have previously used the mac addresss method on the 2960.  Have you tried a differnt code rev?

FWIW, while using "class-default" or a MAC filter would be logical ways
to avoid IPv4 dependencies, neither seems to work, although both could
be applied to an interface. This is unlike class-maps which reference
IPv6 ACLs, which are accepted without errors, along with policy maps
which reference them, but any service-policy statement on the interface
is silently ignored and never shows up in the configuration.

Test results:
    class-default throttles IPv4 but not IPv6.
    ANY-MAC does not throttle IPv4 or IPv6. 

cisco WS-C2960-24TT-L (PowerPC405) processor (revision D0) with 65536K
bytes of memory.
Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version
12.2(58)SE2, RELEASE SOFTWARE (fc1)

So I repeat the question... what is the cheapest Cisco switch with gig
uplinks which supports IPv6 ingress filtering and policing, or, lacking
a definitive answer, is there a feature to check for in the software
advisor or other publicly available resource that reflects this critical

Currently filtering and policing user traffic on Cisco 2960 switches and discovered the hard way that the ingress policy ONLY applies itself to IPv4 packets and only IPv4 access-groups can be applied to an interface. What Cisco switches do I have to upgrade to in order to filter and police ALL customer traffic and not just IPv4 traffic?
