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).
