IPSEC: SPD counters in the stats sgement
- return the stats_index of each SPD in the create API call - no ip_any in the API as this creates 2 SPD entries. client must add both v4 and v6 explicitly - only one pool of SPD entries (rhter than one per-SPD) to support this - no packets/bytes in the dump API. Polling the stats segment is much more efficient (if the SA lifetime is based on packet/bytes) - emit the policy index in the packet trace and CLI commands.
