mac80211: Remove TSF atomic requirement from the documentation (7b08b3b4) · Commits · 戴 / test

The atomic requirement for the TSF callbacks is outdated. get_tsf() is only called by ieee80211_rx_bss_info() which is indirectly called by the work queue ieee80211_sta_work(). In the same context are called several other non-atomic functions, too. And the atomic requirement causes problems for drivers of USB wifi cards. Signed-off-by:
