Originally wireguard doesn't support async mode for decryption packets. This patch add async mode for decryption in wireguard. In addition, it contains some performance improvement such as prefetching packet header and reducing the number of current time function calls. Type: improvement Signed-off-by: Gabriel Oginski <gabrielx.oginski@intel.com> Change-Id: Ieba6ae0078f3ff140c05b517891afb57232b3b7d
