From: "andrea.merello" <andrea.merello@xxxxxxxxx>
HW Specifications says this register has to be written whenever the NIC joins
(or creates) a network (BSS and IBSS).
I suspect that not writing the beacon interval register is probably not a
big issue (probably related to functions not used in the driver right now).
Possibly power-save and HW beaconing.
But I'm not sure it is only needed for that purposes..
On the other hand I'm sure writing it will not hurt anyway.
This patch adds register write on beacon interval changes.
