ieee80211_tx_status(9) [centos man page]

IEEE80211_TX_STATUS(9)					  The basic mac80211 driver inte				    IEEE80211_TX_STATUS(9)

NAME
ieee80211_tx_status - transmit status callback SYNOPSIS
void ieee80211_tx_status(struct ieee80211_hw * hw, struct sk_buff * skb); ARGUMENTS
hw the hardware the frame was transmitted by skb the frame that was transmitted, owned by mac80211 after this call DESCRIPTION
Call this function for all transmitted frames after they have been transmitted. It is permissible to not call this function for multicast frames but this can affect statistics. This function may not be called in IRQ context. Calls to this function for a single hardware must be synchronized against each other. Calls to this function, ieee80211_tx_status_ni and ieee80211_tx_status_irqsafe may not be mixed for a single hardware. Must not run concurrently with ieee80211_rx or ieee80211_rx_ni. AUTHOR

IEEE80211_GET_BUFFER(9) 				     Advanced driver interface					   IEEE80211_GET_BUFFER(9)

NAME
ieee80211_get_buffered_bc - accessing buffered broadcast and multicast frames SYNOPSIS
struct sk_buff * ieee80211_get_buffered_bc(struct ieee80211_hw * hw, struct ieee80211_vif * vif); ARGUMENTS
hw pointer as obtained from ieee80211_alloc_hw. vif struct ieee80211_vif pointer from the add_interface callback. DESCRIPTION
Function for accessing buffered broadcast and multicast frames. If hardware/firmware does not implement buffering of broadcast/multicast frames when power saving is used, 802.11 code buffers them in the host memory. The low-level driver uses this function to fetch next buffered frame. In most cases, this is used when generating beacon frame. RETURN
A pointer to the next buffered skb or NULL if no more buffered frames are available. NOTE
buffered frames are returned only after DTIM beacon frame was generated with ieee80211_beacon_get and the low-level driver must thus call ieee80211_beacon_get first. ieee80211_get_buffered_bc returns NULL if the previous generated beacon was not DTIM, so the low-level driver does not need to check for DTIM beacons separately and should be able to use common code for all beacons.
