2012-06-22mwifiex: fix bugs in event handling codeAmitkumar Karwar3-11/+10
This patch ensures uniformity in event skb sent by interface code (USB/PCIe/SDIO) which automatically fixes following bugs. 1) For USB interface, same buffer is reused for receiving cmd and events from firmware. While handling events, we perform skb_pull(skb, 4) to remove event header. Corresponding skb_push() call is missing while submitting the buffer. 2) For PCIe interface, event skb is passed with event header. Recently added uAP events EVENT_UAP_STA_ASSOC, EVENT_UAP_STA_DEAUTH will not work for PCIe, as they assume event skb points to event body.

2012-06-22mwifiex: fix WPS eapol handshake failureStone Piao1-0/+1
After association, STA will go through eapol handshake with WPS enabled AP. It's observed that WPS handshake fails with some 11n AP. The reason for the failure is that the eapol packet is sent via 11n frame aggregation. The eapol packet should be sent directly without 11n aggregation. This patch fixes the problem by adding WPS session control while dequeuing Tx packets for transmission.

2012-06-22mwifiex: fix 11n rx packet drop issueStone Piao3-2/+12
Currently we check the sequence number of last packet received against start_win. If a sequence hole is detected, start_win is updated to next sequence number. Since the rx sequence number is initialized to 0, a corner case exists when BA setup happens immediately after association. As 0 is a valid sequence number, start_win gets increased to 1 incorrectly. This causes the first packet with sequence number 0 being dropped. Initialize rx sequence number as 0xffff and skip adjusting start_win if the sequence number remains 0xffff. The sequence number will be updated once the first packet is received.

2012-06-19mwifiex: fix uAP TX packet timeout issueAvinash Patil1-7/+3
When running heavy traffic we stop the tx queue if the pending packet count reaches certain threshold. Later, the tx queue should be woken up as soon as the packet count falls below the threshold. Current code wakes TX queue up on STA interface only. Removing the check for STA interface will allow both STA and AP interfaces to resume transmit when tx_pending count becomes low.

Test procedure: 1. Start AP with security setting (e.g. WPA2) 2. Stop AP 3. Start AP with open security Here it's observed that privacy is enabled in beacons and probe responses.

This error is corrected here. 2) Rename "network_tsf" to "fw_tsf" 3) Make use of u64 variable instead of an array of u8/u32 to save parsed "timestamp" information. 4) Use timestamp provided to stack in scan results using cfg80211_inform_bss() while associating.

2012-04-10mwifiex: don't use IEEE80211_MAX_QUEUESJohannes Berg2-5/+5
IEEE80211_MAX_QUEUES is an internal mac80211 value, it is not guaranteed to be always 4. The firmware API in mwifiex almost certainly doesn't care about mac80211 changing though, so mwifiex shouldn't use this value. Maybe it should use IEEE80211_NUM_ACS instead and that is what I'm doing here as at least that value will probably never change, but maybe it should have its own define instead.

2012-04-10mwifiex: add set_cqm_rssi_config handler supportAmitkumar Karwar7-0/+241
In this handler LOW_RSSI and HIGH_RSSI events are subscribed to FW using provided threshold value so that FW will monitor connection quality and trigger any of these events. Driver will notify cfg80211 about connection quality based on inputs from FW and provided hysteresis.
