Track the count of associated devices. Limit the number of associations
using the value provided by the user if any. If we reach the maximum
number of associations, we tell the device we are at capacity. If the
user do not want to accept any more associations, it may specify the
value 0 to the maxi

Devices may decide to disassociate from their coordinator for different
reasons (device turning off, coordinator signal strength too low, etc),
the MAC layer just has to send a disassociation notification.
If the ack of the disassociation notification is not received, the
device may consider itsel
Coordinators may have to handle association requests from peers which
want to join the PAN. The logic involves:
- Acknowledging the request (done by hardware)
- If requested, a random short address that is free on this PAN should
be chosen for the device.
- Sending an association response with th
Introduce structures to describe peer devices in a PAN as well as a few
related helpers. We basically care about:
- Our unique parent after associating with a coordinator.
- Peer devices, children, which successfully associated with us.

Coordinators may refuse associations. We need a user input for
that. Let's add a new netlink command which can provide a maximum number
of devices we accept to associate with as a first step. Later, we could
also forward the request to userspace and check whether the association
should be accepted
Soon association and disassociation will be implemented, which will
require to be able to either change the PAN ID from 0x to a real
value when association succeeded, or to reset the PAN ID to 0x upon
disassociation. Let's allow to do that manually for now.

Users may decide to associate with a peer, which becomes our parent
coordinator. Let's add the necessary netlink support for this.

Upon request, we must be able to provide to the user the list of
associations currently in place. Let's add a new netlink command and

A device may decide at some point to disassociate from a PAN, let's
introduce a netlink command for this purpose.

Peers may decided to disassociate from us, their coordinator, in this
case they will send a disassociation notification which we must
acknowledge. If we don't, the peer device considers itself disassociated
anyway. We also need to drop the reference to this child from our
internal structures.

Joining a PAN officially goes by associating with a coordinator. This
coordinator may have been discovered thanks to the beacons it sent in
the past. Add support to the MAC layer for these associations, which
require:
- Sending an association request
- Receiving an association response
