Re: [PATCH wireless-next] wifi: brcmfmac: allow opting into PM_MAX power management

Hello,
I would like to withdraw this patch.
Further testing on BCM4364 showed intermittent latency spikes of about
50-250 ms with PM_MAX. The connection can work normally for extended
periods, but the issue is reproducible and disappears after switching
back to PM_FAST. This invalidates my earlier statement that I had
observed no latency regression.
Given this trade-off, I no longer think exposing PM_MAX through this new
module parameter is worthwhile, and I do not plan to send a v2. Please
drop the patch.

Sorry for the noise, and thanks for your time.
Regards,
Alexander
