STRUCT 
TID_AMPDU_RX(9) Internals STRUCT TID_AMPDU_RX(9) NAME
struct_tid_ampdu_rx - TID aggregation information (Rx). SYNOPSIS
struct tid_ampdu_rx { struct rcu_head rcu_head; spinlock_t reorder_lock; struct sk_buff ** reorder_buf; unsigned long * reorder_time; struct timer_list session_timer; struct timer_list reorder_timer; unsigned long last_rx; u16 head_seq_num; u16 stored_mpdu_num; u16 ssn; u16 buf_size; u16 timeout; u8 dialog_token; }; MEMBERS
rcu_head RCU head used for freeing this struct reorder_lock serializes access to reorder buffer, see below. reorder_buf buffer to reorder incoming aggregated MPDUs reorder_time jiffies when skb was added session_timer check if peer keeps Tx-ing on the TID (by timeout value) reorder_timer releases expired frames from the reorder buffer. last_rx jiffies of last rx activity head_seq_num head sequence number in reordering buffer. stored_mpdu_num number of MPDUs in reordering buffer ssn Starting Sequence Number expected to be aggregated. buf_size buffer size for incoming A-MPDUs timeout reset timer value (in TUs). dialog_token dialog token for aggregation session DESCRIPTION
This structure's lifetime is managed by RCU, assignments to the array holding it must hold the aggregation mutex. The reorder_lock is used to protect the members of this struct, except for timeout, buf_size and dialog_token, which are constant across the lifetime of the struct (the dialog token being used only for debugging).

STRUCT 
IEEE80211_TX_(9) The basic mac80211 driver inte STRUCT IEEE80211_TX_(9) NAME
struct_ieee80211_tx_rate - rate selection/status SYNOPSIS
struct ieee80211_tx_rate { s8 idx; u16 count:5; u16 flags:11; }; MEMBERS
idx rate index to attempt to send with count number of tries in this rate before going to the next rate flags rate control flags (enum mac80211_rate_control_flags) DESCRIPTION
A value of -1 for idx indicates an invalid rate and, if used in an array of retry rates, that no more rates should be tried. When used for transmit status reporting, the driver should always report the rate along with the flags it used. struct ieee80211_tx_info contains an array of these structs in the control information, and it will be filled by the rate control algorithm according to what should be sent. For example, if this array contains, in the format { <idx>, <count> } the information { 3, 2 }, { 2, 2 }, { 1, 4 }, { -1, 0 }, { -1, 0 } then this means that the frame should be transmitted up to twice at rate 3, up to twice at rate 2, and up to four times at rate 1 if it doesn't get acknowledged. Say it gets acknowledged by the peer after the fifth attempt, the status information should then contain { 3, 2 }, { 2, 2 }, { 1, 1 }, { -1, 0 } ... since it was transmitted twice at rate 3, twice at rate 2 and once at rate 1 after which we received an acknowledgement.
