Hi, There are 2 similar operations in the struct cfg80211_ops: remain_on_channel() and mgmt_tx(). Actually, mgmt_tx() when called for off-channel operation, is the same as remain_on_channel() except it transmits frame at the beginning. What I am interesting about, is notifications to cfg80211. For remain_on_channel(), there are 2: cfg80211_ready_on_channel() when channel tuned, and cfg80211_remain_on_channel_expired() when tuned off requested channel. In contrast, if mgmt_tx() called for off-channel with duration, 2 above notifications are not used. Instead, only cfg80211_mgmt_tx_status() called after tx. My question is why don't mgmt_tx() call cfg80211_ready_on_channel() and cfg80211_remain_on_channel_expired() ? It seems logical to notify about off-channel status. Otherwise, how can upper layers know when off-channel started/finished in context of mgmt_tx()? Comments?
