Subject: mac80211: changing number of queues in ops->start
Date: Tue, 7 Apr 2009 20:24:41 +0200	[thread overview]
Message-ID: <200904072024.41910.mb@bu3sch.de> (raw)

I'm wondering how to implement QoS capability runtime detection
in a mac80211 driver.

In b43 we don't know at ieee80211_register time whether the firmware does
support QoS or not, because it's not loaded yet. (Reasons for not loading
it that early are issues with builtin-b43, etc...).
So we don't know whether we are going to load opensource fw (no QoS) or
proprietary fw (QoS capable).
But it seems that mac80211 requires to set hw->queues before ieee80211_register.

So what I'd need is a way to change the number of possible queues from within
the ops->start handler.

Any ideas?
