enhancement

Currently I can set the power management value for wlan (network cyw43) with the config function. But I can't query the current value. It would be useful to be able to do this for debugging.

applies to network cyw43 wifi
Requires a change to the driver https://github.com/georgerobotics/cyw43-driver/pull/8
I will push a change.

Description

Trying to disable PowerManagement on a esp board acting as client WiFi.

The last doc says:

Constants
WLAN.PM_PERFORMANCE
WLAN.PM_POWERSAVE
WLAN.PM_NONE

I tried from REPL:

from network import *
nic = WLAN(STA_IF)
nic.config(pm = WLAN.PM_NONE)

dir(nic)
['__class__', 'PM_NONE', 'PM_PERFORMANCE', 'PM_POWERSAVE', 'active', 'config', 'connect', 'disconnect', 'ifconfig', 'isconnected', 'scan', 'status']

Questions:

So the attributes are available also on the nic instance: is it wanted or is just a leftover from the past ?
esp32: do these attributes make obsolete the previous setting listen_interval ?
