WiFi throughput drops drastically when BT is turned on, BT and WiFi are simultaneously transmitting/receiving traffic. This is particularly true when BT has higher priority over WiFi, and hence the device defers TX frames. The AP assumes that the channel is bad and reduces the data rate, implying longer airtime, which exacerbates the problem further, resulting ultimately in what is popularly called the "death-spiral" phenomenon. The use of PS-poll in such scenarios guarantees a low but consistent throughput. Since the death-spiral phenomenon is observed only when the RSSI is low, use PS-poll only when RSSI is low and disable when high, with a known hysterisis. This feature specifies the high and low thresholds and implements the callbacks registered with mac80211, which will be called when threshold events occur. iwlwifi: dynamic pspoll: optimize rssi monitor code Signed-off-by:

mac80211 maintains a running average of the RSSI when a STA is associated to an AP. Report threshold events to any driver that has registered callbacks for getting RSSI measurements. Implement callbacks in mac80211 so that driver can set thresholds. Add callbacks in mac80211 which is invoked when an RSSI threshold event occurs. mac80211: add tracing to rssi_reports api and remove extraneous fn argument mac80211: scale up rssi thresholds from driver by 16 before storing Signed-off-by:

Now, there are only two functions to send a host command: * send_cmd that receives a iwl_host_cmd * send_cmd_pdu that builds the iwl_host_cmd itself and received flags The flags CMD_ASYNC / CMD_SYNC / CMD_WANT_SKB are not changed by the API functions. Kill the unused flags CMD_SIZE_NORMAL / CMD_NO_SKB on the way. Signed-off-by:

Tx free functions move to the transport layer. Unify the functions that deal with tx queues and cmd queue. Since the CMD queue is not fully allocated, but uses the q->n_bd / q->window trick, the release flow of TX queue and CMD queue was different. iwlagn_txq_free_tfd receives now the index of the TFD to be freed, which allows to unify the release flow for all the queues.

There can 3 reasons for the "command reject" reply produced by the stack. Each such reply should be accompanied by the relevand data ( as defined in spec. ). Currently there is one instance of "command reject" reply with reason "invalid cid" wich is fixed. Also, added clean-up definitions related to the "command reject" replies. Signed-off-by:

This will be useful when userspace wants to restrict some kinds of operations based on the length of the key size used to encrypt the link. Signed-off-by:

Vinicius Costa Gomes authored
In some cases it will be useful having the key size used for encrypting the link. For example, some profiles may restrict some operations depending on the key length. The key size is stored in the key that is passed to userspace using the pin_length field in the key structure. For now this field is only valid for LE controllers. 3.0+HS controllers define the Read Encryption Key Size command, this field is intended for storing the value returned by that command.

As the key format has changed to something that has a dynamic size, the way that keys are received and sent must be changed. The structure fields order is changed to make the parsing of the information received from the Management Interface easier. Signed-off-by:

Before implementing SM key distribution, the pairing features exchange must be better negotiated, taking into account some features of the host and connection requirements. If we are in the "not pairable" state, it makes no sense to exchange any key. This allows for simplification of the key negociation method. Signed-off-by:

As the LTK (the new type of key being handled now) has more data associated with it, we need to store this extra data and retrieve the keys based on that data. Methods for searching for a key and for adding a new LTK are introduced here. Signed-off-by:

We need these changes because SMP keys may have more information associated with them, for example, in the LTK case, it has an encrypted diversifier (ediv) and a random number (rand). Signed-off-by:

This adds support for generating and distributing all the keys specified in the third phase of SMP. This will make possible to re-establish secure connections, resolve private addresses and sign commands. For now, the values generated are random. Signed-off-by:

In XMIT path, the skb that we get from the kernel itself is not aligned with 4-byte boundary on some embedded platforms. Had it not been the presence of tx_pkt_offset field in txpd, 4 byte memory alignment was not possible without memmove of entire skb. And that would have increased MIPS instead of reducing. With this patch few memory cycles can be saved while fetching interface header and txpd structure because of 4 bytes memory alignment. Reported-by:

Debugfs command 'info' shows wrong interface type. The regression occurred due to commit eecd8250 (mwifiex: remove MWIFIEX_BSS_MODE_ macros) in which we replaced MWIFIEX_BSS_MODE_* macros by NL80211_IFTYPE_*, for example, MWIFIEX_BSS_MODE_IBSS (2) --> NL80211_IFTYPE_ADHOC (1) The issue is fixed by swapping static character array used to display interface type information.
