Subject: suspend/resume support in mac80211
Date: Sun, 05 Aug 2007 21:50:17 +0200	[thread overview]
Message-ID: <1186343417.8459.23.camel@localhost> (raw)

Hi,

we have recently been struggling with getting suspend/resume working in
rt2x00. A few questions:

1. What is the recommended scheme for implementing suspend/resume with
mac80211? Some drivers (p54, iwlwifi) call ieee80211_stop_queues().
rt2x00 is currently doing so, but it doesn't seem to be enough: mac80211
calls back into rt2x00 while the device is suspended, resulting in
chaos.

2. Are there any mac80211 drivers that suspend/resume properly? Also
when associated?

3. Shouldn't mac80211 be made suspend/resume-aware (AFAIK it is not), so
we can do things like disassociating during suspend and reassociating
when resuming? I'd like something in the spirit of
netif_device_detach()/netif_device_attach(). Comments?

Cheers,

Mattias
