Currently, modular tokenring ("tr") lacks a license and fails to load:
tr: module license 'unspecified' taints kernel.
tr: Unknown symbol proc_net_fops_create
Beacuse of this, no tokenring driver can load if it depends on modular
tr. Fix this by adding GPL module license as it is in the kernel.
With this fix, tr module loads fine and tms380 driver also loads. Well,
it does'nt work but that's a different bug.

The callers of netlink_set_err() currently pass a negative value
as parameter for the error code. However, sk->sk_err wants a
positive error value. Without this patch, skb_recv_datagram() called
by netlink_recvmsg() may return a positive value to report an error.
Another choice to fix this is to change callers to pass a positive
error value, but this seems a bit inconsistent and error prone
to me. Indeed, the callers of netlink_set_err() assumed that the
(usual) negative value for error codes was fine before this patch :).
This patch also includes some documentation in docbook format
for netlink_set_err() to avoid this sort of confusion.

The limitation to only 1500 byte mtu's limits the utility of the veth
device for testing routing. So implement implement a configurable
MTU.
For consistency I drop packets on the receive side when they are
larger than the MTU. I count those drops. And I allow
a little padding for vlan headers.
I also test the mtu when a new device is created with netlink
because that path currently bypasses the current mtu setting
code.

It turns out that net_alive is unnecessary, and the original problem
that led to it being added was simply that the icmp code thought
it was a network device and wound up being unable to handle packets
while there were still packets in the network namespace.
Now that icmp and tcp have been fixed to properly register themselves
this problem is no longer present and we have a stronger guarantee
that packets will not arrive in a network namespace then that provided
by net_alive in netif_receive_skb. So remove net_alive allowing
packet reception run a little faster.
Additionally document the strong reason why network namespace cleanup
is safe so that if something happens again someone else will have
a chance of figuring it out.

Recently I had a kernel panic in icmp_send during a network namespace
cleanup. There were packets in the arp queue that failed to be sent
and we attempted to generate an ICMP host unreachable message, but
failed because icmp_sk_exit had already been called.
The network devices are removed from a network namespace and their
arp queues are flushed before we do attempt to shutdown subsystems
so this error should have been impossible.
It turns out icmp_init is using register_pernet_device instead
of register_pernet_subsys. Which resulted in icmp being shut down
while we still had the possibility of packets in flight, making
a nasty NULL pointer deference in interrupt context possible.
Changing this to register_pernet_subsys fixes the problem in
my testing.

When a network namespace is destroyed the network interfaces are
all unregistered, making addrconf_ifdown called by the netdevice
notifier.
In the other hand, the addrconf exit method does a loop on the network
devices and does addrconf_ifdown on each of them. But the ordering of
the netns subsystem is not right because it uses the register_pernet_device
instead of register_pernet_subsys. If we handle the loopback as
any network device, we can safely use register_pernet_subsys.
But if we use register_pernet_subsys, the addrconf exit method will do
exactly what was already done with the unregistering of the network
devices. So in definitive, this code is pointless.
I removed the netns addrconf exit method and moved the code to the
addrconf cleanup function.

(sctp: Fix the RTO-doubling on idle-link heartbeats)
broke the RTO doubling for data retransmits. If the
heartbeat was sent before the data T3-rtx time, the
the RTO will not double upon the T3-rtx expiration.
Distingish between the operations by passing an argument
to the function.
Additionally, Wei Youngjun pointed out that our treatment
of requested HEARTBEATS and timer HEARTBEATS is the same
wrt resetting congestion window. That needs to be separated,
since user requested HEARTBEATS should not treat the link
as idle.

Adding "ethtool -d" support. Due to the complexity of the FW and HW, there are a
lot of different regions in the chip - to keep the code as clean as possible,
the ranges were put in an H file. Some areas cannot be read if the driver is
running - so by default, the driver will not access those areas - but any
programmer facing a problem will be able to easily manipulate the driver to
extract full dump. The full dump can also be used with kernel dump modules in
