crypto: skcipher - Change default sync geniv on SMP to eseqiv
As it stands we use chainiv for sync algorithms and eseqiv for async algorithms. However, when there is more than one CPU chainiv forces all processing to be serialised which is usually not what you want. Also, the added overhead of eseqiv isn't that great. Therefore this patch changes the default sync geniv on SMP machines to eseqiv. For the odd situation where the overhead is unacceptable then chainiv is still available as an option. Note that on UP machines chainiv is still preferred over eseqiv for sync algorithms. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
