wireguard: add async mode for encryption packets
Originally wireguard doesn't support async mode for encryption packets. This patch add async mode for encryption in wireguard and also adds support chacha20-poly1305 algorithm in cryptodev for async handler. In addition it contains new command line to activate async mode for wireguard: set wireguard async mode on|off and also add new command to check active mode for wireguard: show wireguard mode Type: improvement Signed-off-by: Gabriel Oginski <gabrielx.oginski@intel.com> Change-Id: I141d48b42ee8dbff0112b8542ab5205268089da6
