this does not work:

modprobe rtl8723ae debug_mask=0xFFFFFFFF debug_level=5 ips=0

but this works:

modprobe rtl8723ae debug_mask=0xFFFFFFFF debug_level=5 swlps=1 fwlps=0

and this works too:

modprobe rtl8723ae debug_mask=0xFFFFFFFF debug_level=5 ips=0 swlps=1 fwlps=0


so I think I should change the default of swlps and fwlps with this patch,
unless someone comes up with a better solution?


Thanks
Bernd.
