Subject: [PATCH] rtw88: raise LPS threshold to 50, for less power consumption
Git-commit: bf9840ccf8efbdac755772501bd05f6662e1d799
Patch-mainline: v5.5-rc1
References: jsc#SLE-13430, bsc#1176741
The LPS threshold was set to 2, means driver will leave LPS
mode if there is more than 2 frames TX/RX for every 2 seconds.
This makes driver enter/leave LPS frequently even if we just
"ping -i1" to the others.
Apparently we do not want to leave LPS mode if there is only
some background traffics or web surfing. By experiment, set
this to 50 is a more reasonable value to lower the over all
power consumption.
