We actually do not need an extra struct device variable, therefore
replacing them with defines that directly get the bat_priv or
net_device. This further reduces the code size in bat_sysfs.c and
especially shortens some macros.

Sysfs configuration options that just took a boolean value
(enable(d)/disable(d)/0/1) and integer setting basically all had the same
structure.

To avoid even more copy and pasting in the future and to make introducing
new configuration parameters for batman-adv simpler, more generic
wrapper functions are being introduced with this commit. They can deal with
boolean and unsigned integer parameters, storing them in the specified
atomic_t variables.

Both sysfs entries and variable names shall be as descriptive as
possible while not exceeding a certain length. This patch renames
bat_priv atomics to be equally descriptive with their according sysfs
entries.

Unifying sysfs and bat_priv atomic names also makes it easier to find
each others pendant.

The reduced ("type"-)information which was previously indicated with a
_enabled for booleans got substituted by a comment in bat_priv.

This patch has also been done in regards for the future BAT_ATTR_*
macros (they only need one name argument instead of a file and variable
name).

By connecting multiple batman-adv mesh nodes to the same ethernet
segment a loop can be created when the soft-interface is bridged
into that ethernet segment. A simple visualization of the loop
involving the most common case - a LAN as ethernet segment:

node1  <-- LAN  -->  node2
   |                   |
 wifi  <-- mesh -->  wifi

Packets from the LAN (e.g. ARP broadcasts) will circle forever from
node1 or node2 over the mesh back into the LAN.

This patch adds the functionality to detect other batman-adv nodes
connected to the LAN and select a 'gateway' to talk to the
non-batman-adv devices on this LAN. All traffic from and to the mesh
will be handled by this gateway to avoid the loop. OGMs received via
the soft-interface are interpreted as 'port announcements' to locate
potential batman-adv nodes. The patch can also deal with vlans on
top of batX and offers a list of LAN neighbors via debugfs.

The unicast_frag_send_skb() function expected 'raw' packets (without any

this function is able to fragment packets that already traveled inside

We call a lot of the netdevice code when holding if_list_lock which will
spin the whole time. This is not necessary because we only want to
protect the access to the list to be serialized. An extra queue can be
used which hold all interfaces which should be removed and then use that
queue without any locks for netdevice cleanup.

eth_type_trans tries to pull data with the length of the ethernet header
from the skb. We only ensured that enough data for the first ethernet
header and the batman header is available in non-paged memory of the skb
and not for the ethernet after the batman header.

eth_type_trans would fail sometimes with drivers which don't ensure that
all there data is perfectly linearised.

This has been checked with checkpatch and there are four
warnings for lines over 80 charactors.

There is one compile warning. This is for a function that is
only used if the rar register driver is needed. There is an
ifdef in a header file that stubs out the rar register driver
if the rar register is not configured.

This driver does add a configuration, which is CONFIG_DX_SEP.
