Fixes for rt5572 chipset driver tested with Linux 3.16.3 based on DPO_RT5572_LinuxSTA_2.6.0.1 Ralink Linux driver.

THe vendor driver for the rt5572 (rt5572sta) is unstable. I am spporting a wireless adatper TP-Link TL-WDN3200 on Linux.

This is work related to linux support for the O2 Joggler.

Linux joggler 3.16.3 #5 SMP Tue Sep 30 23:28:07 BST 2014 i686 i686 i686 GNU/Linux

TP-Link WDN3200 testing shows that there are frequent disconnects.

This is my attampt to solve these issues.
