In the answer by Chili555 for How do I create a system file /etc/modprobe.d/ath9k.conf? it is shown that you can create a config file for a kernel module . Now the question is how do I verify that the options set in that config file have taken effect after sudo modprobe ath9k ?
Specific option that I am trying to check is ps_enable. However, doing the following
$ modinfo ath9k | grep ps_enable
parm: ps_enable:Enable WLAN PowerSave (int)
only explains what the parameter is and not its current value.

Apparently such information is contained within /sys filesystem. According to Gilles's answer on the relevant post, in order to find the driver in use by interface you would execute
readlink /sys/class/net/wlan0/device/driver
which would provide the relative path as in
../../../../bus/pci/drivers/ath5k
In my case due to systemd and predictive interface naming, the interface is named differently and produces
$ readlink /sys/class/net/wlp2s0/device/driver
../../../../bus/pci/drivers/ath9k
The resulting directory path contains subdirectories module/parameters/ where there will be files for each parameter containing their current value. Thus, if I edit the /etc/modprobe/ath9k.conf file and reinsert the module, the result is as follows:
# After editing the conf file to set parameter to 1
$ sudo sh -c 'modprobe -r ath9k ; sleep 3; modprobe ath9k'
$ sudo cat /sys/class/net/wlp2s0/device/driver/../../../../bus/pci/drivers/ath9k/module/parameters/ps_enable
1
# after editing the file and setting parameter to 0
$ sudo sh -c 'modprobe -r ath9k ; sleep 3; modprobe ath9k'
$ sudo cat /sys/class/net/wlp2s0/device/driver/../../../../bus/pci/drivers/ath9k/module/parameters/ps_enable
0
The command can be combined as well.
$ cat "$(readlink -f /sys/class/net/wlp2s0/device/driver/)"/module/parameters/ps_enable
0
If you do have desktop environment and dbus running, as well as qdbus or dbus-send installed, such information can be queried via Network Manager's dbus interface ( though it requires figuring out the object path of each individual device, and probably would be better written in Python or C )
$ qdbus --system org.freedesktop.NetworkManager /org/freedesktop/NetworkManager/Devices/14 org.freedesktop.NetworkManager.Device.Driver
