mac80211: add functions to create PS Poll and Nullfunc templates
Some hardware, for example wl1251 and wl1271, handle the transmission of power save related frames in hardware, but the driver is responsible for creating the templates. It's better to create the templates in mac80211, that way all drivers can benefit from this. Add two new functions, ieee80211_pspoll_get() and ieee80211_nullfunc_get() which drivers need to call to get the frame. Drivers are also responsible for updating the templates after each association. Also new struct ieee80211_hdr_3addr is added to ieee80211.h to make it easy to calculate length of the Nullfunc frame. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W.
