Currently, when the nx-842-pseries driver loads, the following message
is emitted:

alg: No test for 842 (842-nx)

It seems like the simplest way to fix this message (other than adding a
proper test) is to just insert the null test into the list in the
testmgr.

As this is a compression algo, it is safe to add fips_allowed = 1 here as 
otherwise the algo is not available in fips=1

Please add some real test vectors instead.

Thanks,

Apologies, hit send too fast. I'll work with Dan on this when he gets
back from vacation.

Back from vacation! :-)

I originally didn't add any test vector for NX 842 because the main
driver was loading before the "platform" (pseries/powernv) drivers,
and the test couldn't run as the platform driver hadn't loaded yet.
That's now fixed so we should be able to add a real test for NX 842
now, I can work on that patch.
