If anyone has any objections, please let me know. ------------------ From: Johannes Berg commit bb512ad0732232f1d2693bb68f31a76bed8f22ae upstream. This reverts commit 24aa11ab8ae03292d38ec0dbd9bc2ac49fe8a6dd. That commit was wrong since it uses data that hasn't even been set up yet, but might be a hold-over from a previous connection. Additionally, it seems like a driver-specific workaround that shouldn't have been in mac80211 to start with.
