From d912bb7677f46d78a3cde8a4afd45a3fca4b34e9 Mon Sep 17 00:00:00 2001 From: Nikos Mavrogiannopoulos Date: Tue, 1 Nov 2011 13:39:56 +0100 Subject: crypto: Add CRYPTO_ALG_KERN_DRIVER_ONLY flag The added CRYPTO_ALG_KERN_DRIVER_ONLY indicates whether a cipher is only available via a kernel driver. If the cipher implementation might be available by using an instruction set or by porting the kernel code, then it must not be set.
