Hello This patch is a try to implement a generic crypto driver statistics. The goal is to have an "ifconfig" for crypto device. Some driver tried to implement this via a debugfs interface. This serie do it directly in the crypto API and give access to stats via the crypto_user(netlink) API. Then an userspace tool will collect information via netlink. Note that this userspace tool is heavily copied from libkcapi and if Stephan Mueller agree, I will made a PR for adding getstat to it.
