Hi,
Don't look for IEEE80211_HW_NEED_DTIM_PERIOD flag after association finishes and advertise DTIM period to all drivers.

1.7.0.4
IEEE80211_HW_NEED_DTIM_PERIOD description says:
* This device needs to know the DTIM period for the BSS before
* associating.
This patch is helpful for drivers that don't need to know DTIM period before association, but need it after association for power save reasons and can't accept roaming delays.
I can see that I am not the only one that had such problems:
