Subject: mac80211 and ath9k channel context

Hi,

The channel context is mentioned in lots of mails and pieces of code,
but its significance or goal is never mentioned. Could someone please be
so kind to elaborate on this?

I believe the channel context is used to provide some hardware
abstraction towards the driver and mac, such that virtual interfaces are
able to work "in parallel" (to their knowledge they are the sole users)
on the hardware, even when they use different channels. When a virtual
interface needs to perform some action (transmission,...), the channel
is set to the corresponding channel of the interface. Furthermore is the
activation of virtual interfaces done in a round robin manner, where
each channel in the channel context is activated at a periodic interval.

Is this about correct, or am I gravely mistaken?

Thanks,

Kind regards,
Wim.
