Configure it for management/ctl frames that are sent in hw. We send them with long preamble atm.
I am working on patches which will help you here. Currently mac80211's handling of short preambles is correct for hostap/master mode but not for a STA.
The interface I'm working on adding will be somewhat similar to the softmac interface. That is, preambles are available on a per-frame basis and the driver also gets a notification when the availability of short preambles changes.
zd1211rw seems to have similar requirements for bcm43xx. The correct behaviour (IMO) is to send frames with long preambles until mac80211 uses the above notification to tell you that short preambles are now allowable. This is how zd1211rw-softmac does it.
I have written the code for the above but have not had time to test it yet. Hopefully within the next few days...
