It is slightly irritating that comments after a long line span over
multiple lines without any code. It is easier to put them before the
actual code and reduce the number of lines which the eye has to read.

hardif_list_lock is unneccessary because we already ensure that no
multiple admin operations can take place through rtnl_lock.
hardif_list_lock only adds additional overhead and complexity.
Critical functions now check whether they are called with rtnl_lock
using ASSERT_RTNL.
It indirectly fixes the problem that orig_hash_del_if() expects that
only one interface is deleted from hardif_list at a time, but
hardif_remove_interfaces() removes all at once and then calls
orig_hash_del_if().

The bridge loop detection for batman-adv allows the bat0 interface
to be bridged into an ethernet segment which other batman-adv nodes
are connected to. In order to also allow multiple VLANs on top of
the bat0 interface to be bridged into the ethernet segment this
patch extends the aforementioned bridge loop detection.

The RCU callback softif_neigh_free_rcu() just calls kfree(), so we can
use kfree_rcu() instead of call_rcu().

The rcu protected macros rcu_dereference() and rcu_assign_pointer()
for the bat_priv->primary_if need to be used, as well as spin/rcu locking.
Otherwise we might end up using a primary_if pointer pointing to already
freed memory.

This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.
For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.
All drivers compiled with make allyesconfig ion x86_64 have been
updated.
Tested: make allyesconfig on x86_64 + e1000e/bnx2x work

Like other virtual interfaces, e.g. br0, we don't need a transmit
queue. Packets should only be queued on real interfaces which are
underneath. In practice this patch makes little difference since the
virtual interfaces can accept packets as fast as they come, but the
patch will avoid bufferbloat questions to the mailling lists in the
future.

When trying to associate a net_device with another net_device which
already exists, batman-adv assumes that this interface is a fully
initialized batman mesh interface without checking it. The behaviour
when accessing data behind netdev_priv of a random net_device is
undefined and potentially dangerous.

When printing the soft interface table the number of entries in the
softif neigh list are first being counted and a fitting buffer
allocated. After that the softif neigh list gets locked again and
the buffer printed - which has the following two issues:
For one thing, the softif neigh list might have grown when reacquiring
the rcu lock, which results in writing outside of the allocated buffer.
Furthermore 31 Bytes are not enough for printing an entry with a vid
of more than 2 digits.
The manual buffering is unnecessary, we can safely print to the seq
directly during the rcu_read_lock().

It might be possible that 2 threads access the same data in the same
rcu grace period. The first thread calls call_rcu() to decrement the
refcount and free the data while the second thread increases the
refcount to use the data. To avoid this race condition all refcount
operations have to be atomic.
