Several users have reported awful latency when powersaving is enabled
with certain access point combinations. It's also reported that the
powersaving feature doesn't provide an ample enough savings to justify
being enabled by default with these issues.
Introduce a module parameter that would control the power saving
behavior. Set it to default as disabled. This mirrors what some other
WLAN drivers like iwlwifi do.

This patch is disabling two different things at the same time:
- Wifi powersaving
- Device hardware powersaving
Have you tried simply disabling 802.11 powersave via nl80211 to mitigate
the issues with affected APs?

Kalle suggested this as well, I will experiment, thanks.
