* mwifiex: Suppress -ENOSR error for data traffic on USBAmitkumar Karwar2015-09-291-1/+1
| | | | | | | | | | | | | We have preallocated buffer pool for Tx data. During high data traffic, all buffers are submitted to USB and driver needs to wait until one of the buffers get available for next Tx packet. "data: -ENOSR is returned" errors is expected in this case. Let's lower the priority of this message.

* mwifiex: fix for p2p broken linkAniket Nagarnaik2015-07-211-1/+21
| | | | | | | | | | | | | | | This patch fixes following issues in p2p code paths. 1) bss role, bss type and connection type was not set correctly for p2p GO and p2p client at couple of places. 2) Driver appends a proprietary header to management frames which will be parsed by our firmware. Later while informing TX status to cfg80211, modified frame buffer was passed to cfg80211_mgmt_tx_status() instead of original one.

* mwifiex: add multi-queue supportAvinash Patil2012-11-141-11/+17
| | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple TX queues inside mwifiex driver. Four different queues according to WMM access categories are defined for each virtual interface. When a packet is received from netdev for transmission, tx pending count for particular queue is incremented and if tx pending count has reached upper water-mark, this queue is stopped instead of stopping all queues. Similarly when a packet is successfully transmitted from device, tx pending count is decremented per queue and if pending count falls below lower water-mark, queue operations are again resumed. This ensures that not all tranmission is blocked if traffic with particular TOS value suddenly increases. Also wake all queues after association/IBSS_join/uAP_BSS_start to enable traffic on all queues.

* mwifiex: fix uAP TX packet timeout issueAvinash Patil2012-06-191-7/+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.
