[Swan-dev] enumcheck-01 fails

[D. Hugh Redelmeier]

It looks to be due to changes to the impair bits.  It is kind of hard to 
decode the output of the test.

Here's a massaged version:

 impair-send-zero-gx
 impair-send-bogus-dcookie
 impair-omit-hash-notify
-impair-omit-hash-notify
+impair-ignore-hash-notify
 impair-ignore-hash-notify-resp
+impair-ikev2-exclude-integ-none
+impair-ikev2-include-integ-none

If this is the new normal, the reference file should be updated.
