VPP-279: Document changes for vnet/vnet/devices
Add doxygen documentation for DPDK crypto CLI command. The move of DPDK to a plugin invalidated the local dir.dox. So moved dpdk/dir.dox to dpdk/device/dir.dox to fix. Change-Id: I229e2921c4b0cdd380021adb520cd2089a376afa Signed-off-by: Billy McFall <bmcfall@redhat.com>
