This patch adds all missing functionalities for nfc except GRXFH. There is so much code because hardware has not a TCAM.
Further hardware rule space is very limited. So I had to extensively use
optimization features. Both reasons lead to the necessity to hold all
online flows in a linked-list.

Ethernet MAC drivers based on phylib (but not using NAPI) can
enable hardware time stamping in phy devices by calling netif_rx()
conditionally based on a call to skb_defer_rx_timestamp().
This commit exports that function so that drivers calling it may
be compiled as modules.

stats_lock is non useless, lets remove it.
Also, ndo_get_stats64() doesnt have to clear the stats, caller takes
care of this.
Note: folding 32bit fields in 64bit one is problematic when one of 32bit
values wraps : SNMP reader will see a ~2^32 back change in a 64bit
value. A future patch should fix this.

Remove the myri_sbus driver. Why?
* There is no possibility of ethernet mode on this adapter, so it's
Myrinet only.
* It won't inter-op with modern versions of Myrinet, and thus can only
work with legacy adapters.
* There are no in-kernel Linux drivers for the PCI version of this
adapter, so it only can work on ~15 year old Sun hardware.
It's long in the tooth, let's take it to the knackers.

Using throw_uevent() is now possible to trigger uevent signal that can
be recognised in userspace. Uevents will be triggered through the
/devices/virtual/net/{MESH_IFACE} kobject.
A triggered uevent has three properties:
- type: the event class. Who generates the event (only 'gw' is currently
defined). Corresponds to the BATTYPE uevent variable.
- action: the associated action with the event ('add'/'change'/'del' are
currently defined). Corresponds to the BATACTION uevent variable.
- data: any useful data for the userspace. Corresponds to the BATDATA
uevent variable.

With the current client announcement implementation, in case of roaming,
an update is triggered on the new AP serving the client. At that point
the new information is spread around by means of the OGM broadcasting
mechanism. Until this operations is not executed, no node is able to
correctly route traffic towards the client. This obviously causes packet
drops and introduces a delay in the time needed by the client to recover
its connections.
A new packet type called ROAMING_ADVERTISEMENT is added to account this
issue.
This message is sent in case of roaming from the new AP serving the
client to the old one and will contain the client MAC address. In this
way an out-of-OGM update is immediately committed, so that the old node
can update its global translation table. Traffic reaching this node will
then be redirected to the correct destination utilising the fresher
information. Thus reducing the packet drops and the connection recovery
delay.

The client announcement mechanism informs every mesh node in the network
of any connected non-mesh client, in order to find the path towards that
client from any given point in the mesh.
The old implementation was based on the simple idea of appending a data
buffer to each OGM containing all the client MAC addresses the node is
serving. All other nodes can populate their global translation tables
(table which links client MAC addresses to node addresses) using this
MAC address buffer and linking it to the node's address contained in the
OGM. A node that wants to contact a client has to lookup the node the
client is connected to and its address in the global translation table.
It is easy to understand that this implementation suffers from several
issues:
- big overhead (each and every OGM contains the entire list of
connected clients)
- high latencies for client route updates due to long OGM trip time and
OGM losses
The new implementation addresses these issues by appending client
changes (new client joined or a client left) to the OGM instead of
filling it with all the client addresses each time. In this way nodes
can modify their global tables by means of "updates", thus reducing the
overhead within the OGMs.
To keep the entire network in sync each node maintains a translation
table version number (ttvn) and a translation table checksum. These
values are spread with the OGM to allow all the network participants to
determine whether or not they need to update their translation table
information.
When a translation table lookup is performed in order to send a packet
to a client attached to another node, the destination's ttvn is added to
the payload packet. Forwarding nodes can compare the packet's ttvn with
their destination's ttvn (this node could have a fresher information
than the source) and re-route the packet if necessary. This greatly
reduces the packet loss of clients roaming from one AP to the next.

The comment for the skb_tx_timestamp() function suggests calling it just
after a buffer is released to the hardware for transmission. However,
for drivers that free the buffer in an ISR, this produces a race between
the time stamp code and the ISR. This commit changes the comment to advise
placing the call just before handing the buffer over to the hardware.
