[PATCH v3 0/4] rtlwifi: Fix issues with rtl8723ae

[Bernd Edlinger]

Currently the rtl8723ae driver is broken (since v4.7).

Connection to AP is lost very often, especially when
the signal level is not very good.

The main issue is the power save mode is basically
not working, and seems to trigger a firmware bug.
So I had to take out the FW LPS mode handling.

While debugging the driver I found a couple related issues,
for instance that the signal level in dm.undec_sm_pwdb
is no longer accurate (may be even much too high) when no more
packets are received, and it increases the likelihood to receive
something if the input gain is set to maximum.

The patch was tested with the rtl8723ae PCI card in my laptop
against a FRITZ!Box 7590 AP -- the WiFi connection works now
very reliable for me.

ChangeLog:

v2: Adjusts the defaults of swlps and fwlps module
parameters to match the firmware capabilities instead of removing
the whole code, so it can be easily re-activated once a firmware
update is available.

v3: Make the title of each patch fit in one line.

  rtl8723ae: Dont use old data for input gain control
  rtl8723ae: Re-introduce the adaptive rate control
  rtlwifi: Don't clear num_rx_inperiod too early
