Implement support for basic ethtool functionality.
Note that ovpn is a virtual device driver, therefore
various ethtool APIs are just not meaningful and thus
not implemented.

In case of UDP links, the local endpoint used to communicate with a
given peer may change without a connection restart.
Add support for learning the new address in case of change.

Sure. I did an unasked-for scripted 'remove_new' removal right after
rc1 for the same reason.
If we have these kinds of big scripted things, right after the merge

Packets received over the socket are forwarded to the user device.
Implementation is UDP only. TCP will be added by a later patch.
Note: no decryption/decapsulation exists yet, packets are forwarded as
they arrive without much processing.

This change introduces the netlink commands needed to add, get, delete
and swap keys for a specific peer.
Userspace is expected to use these commands to create, inspect (non
sensitive data only), destroy and rotate session keys for a specific
peer.

Designate the "MODULE_${modname}" symbol namespace to mean: 'only
export to the named module'.
Notably, explicit imports of anything in the "MODULE_" space is
forbidden. Modules implicitly get the "MODULE_${modname}" namespace
added.

Blast from the past: https://lists.linuxcoding.com/kernel/2007-q4/msg
An ovpn interface configured in MP mode will keep carrier always
on and let the user decide when to bring it administratively up and
down.
This way a MP node (i.e. a server) will keep its interface always
up and running, even when no peer is connected.

Clean up the existing export namespace code along the same lines of
33def8498fdd ("treewide: Convert macro and uses of __section(foo) to
__section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

Whenever a peer is deleted, send a notification to userspace so that it
can react accordingly.
This is most important when a peer is deleted due to ping timeout,
because it all happens in kernelspace and thus userspace has no direct
way to learn about it.

Instead of only accepting "MODULE_${name}", extend it with a comma
separated list of module names and add tail glob support.
That is, something like: "MODULE_foo-*,bar" is now possible.

Packets sent over the ovpn interface are processed and transmitted to the

Implementation is UDP only. TCP will be added by a later patch.
Note: no crypto/encapsulation exists yet. Packets are just captured and

This is the 12th version of the patchset.
Hopefully there are no major flaws that will require more resendings.
I am sure we'll have plenty of time to polish up all bells and whistles
:-)
@Sergey, at the end I think I took in all your suggested changes, maybe
with some adaptations.
