[CRYPTO]: Add cipher speed tests
From: Reyk Floeter <reyk@vantronix.net> I recently had the requirement to do some benchmarking on cryptoapi, and I found reyk's very useful performance test patch [1]. However, I could not find any discussion on why that extension (or something providing a similar feature but different implementation) was not merged into mainline. If there was such a discussion, can someone please point me to the archive[s]? I've now merged the old patch into 2.6.12-rc1, the result can be found attached to this email. [1] http://lists.logix.cz/pipermail/padlock/2004/000010.html Signed-off-by: Harald Welte <laforge@gnumonks.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
