It's hw switched as long as the GRE tunnel source is unique. Look
at the configuration guide for the sup720 it clearly explains that.

That's a bit different as the VPNSM can take over both the GRE
and the IPSEC if you are doing GRE over IPSEC.

As for the raw numbers I don't know. It's high for raw GRE as it's
done in hardware so whatever the number is for the sup720 it
should be able to do GRE at those rates.

Same as for the VPNSM along with normal encryption rates.
