}; RCU head used for freeing this struct
serializes access to reorder buffer, see below.
buffer to reorder incoming aggregated MPDUs
jiffies when skb was added
check if peer keeps Tx-ing on the TID (by timeout value)
releases expired frames from the reorder buffer.
head sequence number in reordering buffer.
number of MPDUs in reordering buffer
Starting Sequence Number expected to be aggregated.
buffer size for incoming A-MPDUs
reset timer value (in TUs).
dialog token for aggregation session
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).
