flow_dissector: Parse batman-adv unicast headers

The batman-adv unicast packets contain a full layer 2 frame in encapsulated form. The flow dissector must therefore be able to parse the batman-adv unicast header to reach the layer 2+3 information.

+--------------------+ | ip(v6)hdr | +--------------------+ | inner ethhdr | +--------------------+ | batadv unicast hdr | +--------------------+ | outer ethhdr | +--------------------+

The obtained information from the upper layer can then be used by RPS to schedule the processing on separate cores. This allows better distribution of multiple flows from the same neighbor to different cores.

batman-adv: Convert packet.h to uapi header

The header file is used by different userspace programs to inject packets or to decode sniffed packets. It should therefore be available to them as userspace header.

Also other components in the kernel (like the flow dissector) require access to the packet definitions to be able to decode ETH_P_BATMAN ethernet packets.

batman-adv: Remove usage of BIT(x) in packet.h

The BIT(x) macro is no longer available for uapi headers because it is defined outside of it (linux/bitops.h). The use of it must therefore be avoided and replaced by an appropriate other representation.

batman-adv: Let packet.h include its headers directly

The headers used by packet.h should also be included by it directly. main.h is currently dealing with it in batman-adv, but this will no longer work when this header is moved to include/uapi/linux/.

batman-adv: Rename batman-adv.h to batadv_genl.h

This file contains the relevant information to let userspace communicate with batman-adv over generic netlink. The relevant genl enums for the attributes and commands have the prefix batadv_genl. Renaming this file to this name therefore represents the content better and avoids confusion with the file which will contain the packet format definitions.

batman-adv: Change nl references to genl

The batman-adv netlink functionality is actually not pure netlink but is using NETLINK_GENERIC and related API. The code should therefore also use this "genl" instead of "nl" to make this more clear.
