Allow drivers or rate control algorithms to specify BlockAck session timeout when initiating an ADDBA transaction. This is useful in cases where maintaining persistent BA sessions does not incur any overhead. The current timeout value of 5000 TUs is retained for all non ath9k/ath9k_htc drivers.

- reduce the number of retransmission attempts for sample rates - sample lower rates less often - do not use RTS/CTS for sampling frames - increase the time between sampling attempts Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This patch fixes two problems with the minstrel_ht rate control algorithms handling of A-MPDU frames: 1. The ampdu_len field of the tx status is not always initialized for non-HT frames (and it would probably be unreasonable to require all drivers to do so). This could cause rate control statistics to be corrupted. We now trust the ampdu_len and ampdu_ack_len fields only when the frame is marked with the IEEE80211_TX_STAT_AMPDU flag. 2. Successful transmission attempts where only recognized when the A-MPDU subframe carrying the rate control status information was marked with the IEEE80211_TX_STAT_ACK flag. If this information happed to be carried on a frame that failed to be ACKed then the other subframes (which may have succeeded) where not correctly registered. We now update rate control statistics regardless of whether the subframe carrying the information was ACKed or not.

The intent was to free "msp->ratelist" here. "msp->sample_table" is always NULL at this point. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

Currently we allocate some memory for each TX aggregation session and additionally keep a state bitmap indicating the state it is in. By using RCU to protect the pointer, moving the state into the structure and some locking trickery we can avoid locking when the TX agg session is fully operational.
