Detailed Description

struct tid_ampdu_tx - TID aggregation information (Tx).

: rcu head for freeing structure : timer for peer's response to addba request : pending frames queue -- use sta's spinlock to protect : dialog token for aggregation session : session timeout value to be filled in ADDBA requests : session state (see above) : initiator of a session stop : TX DelBA frame when stopping : reorder buffer size at receiver : ssn of the last failed BAR tx attempt : BAR needs to be re-sent

This structure's lifetime is managed by RCU, assignments to the array holding it must hold the aggregation mutex.

The TX path can access it under RCU lock-free if, and only if, the state has the flag HT_AGG_STATE_OPERATIONAL set. Otherwise, the TX path must also acquire the spinlock and re-check the state, see comments in the tx code touching it.
