CR00021262 IPsec - This enhancement has improved router or switch performance when:
■ multiple IPsec policies exist. In particular, having two policies causes
much less of a reduction in performance.
■ a single channel exists with bidirectional traffic (i.e. the single channel is
both encoding and decoding packets).
