* a fix for the stuck TFD queue mechanism - it was producing
   noisy false alarms
 * a fix for the NIC prepare flow that prevented the driver
   from being able to access the device on certain systems
 * a fix for the scan prority handling which allows the
   regular scan to run even if a scheduled scan is already
   running
 
 rsi:
 
 * fix firmware load DMA regression
 
 b43:
 
 * fix extpa_gain check for 2GHz
 
 rtlwifi:
 
 * fix NULL dereference when PCI driver used as an AP
 * add missing module parameter declaration for rtl8723be_mod_params.msi_support
