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

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 remove that code.

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.

Bernd Edlinger (4):
   rtlwifi: rtl8723ae: Take the FW LPS mode handling out
   rtlwifi: rtl8723ae: Don't use dm.undec_sm_pwdb for input gain control
        when no beacon was received in the connected state.
   rtlwifi: rtl8723ae: Re-introduce
     rtl8723e_dm_refresh_rate_adaptive_mask
   rtlwifi: Move the clearing of rtlpriv->link_info.num_rx_inperiod in
      rtl_watchdog_wq_callback a few lines down.
