crypto: testmgr - Allow implementation-specific tests
Herbert Xu [Thu, 2 Jul 2009 08:32:12 +0000 (16:32 +0800)]
This patch adds the support for testing specific implementations.
This should only be used in very specific situations.  Right now
this means specific implementations of random number generators.
