[PATCH 04/16] mac80211: Don't encrypt beacons

[Ivo van Doorn <ivdoorn@gmail.com>]

Beacons shouldn't be encryped, so mac80211 should set
the IEEE80211_TX_CTL_DO_NOT_ENCRYPT flag in tx info flags.
Otherwise the driver will cause a NULL pointer dereference
when it tries to access the info->control.hw_key which isn't
configured.
