* mwifiex: adjust high/low water marks for tx_pending queueMarc Yang2011-05-19
| | | | | | | | | This is to fix an issue that the throughput of the higher priority stream gets dropped when a lower priority stream is present. Signed-off-by: Marc Yang <yangyang@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mwifiex: CPU mips optimization with NO_PKT_PRIO_TIDMarc Yang2011-05-19
| | | | | | | | | | If we go through the entire for loop in mwifiex_wmm_get_highest_priolist_ptr() and don't find any packets, set highest_queued_prio to NO_PKT_PRIO_TID (< LOW_PRIO_TID).

* mwifiex: reduce CPU usage by tracking highest_queued_prioMarc Yang2011-05-19
| | | | | | | | | | | | This patch adds highest_queued_prio to track priority of packets as they are enqueued so that mwifiex_wmm_get_highest_priolist_ptr() starts checking at the first level where we have packets, instead of the highest. The function also lowers priority value to the level where first packet is found. Signed-off-by: Marc Yang <yangyang@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

* mwifiex: reduce CPU usage by tracking tx_pkts_queuedMarc Yang2011-05-19
| | | | | | | | | | This patch adds tx_pkts_queued to track number of packets being enqueued & dequeued so that mwifiex_wmm_lists_empty() evaluation is lightweight.

* mwifiex: remove mwifiex_recv_complete functionAmitkumar Karwar2011-05-12
| | | | | | | | | | | | | | The function - increments dropped rx_packet count if status code passed to it is "-1". - frees SKB buffer. But currently the function is being called with "0" status code. This patch replaces above function by dev_kfree_skb_any() call. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

* mwifiex: fix simultaneous assoc and scan issueAmitkumar Karwar2011-05-05
| | | | | | | | | | | | | | | | | | | | | When scan and assoc (infra/ibss) commands are simultaneously given in two terminals, association response is erroneously served while serving the scan response. mwifiex_cfg80211_results() is the common routine for sending ioctl (scan, assoc etc.) results to cfg80211 stack. In above scenario even if the common routine is called for scan ioctl context, it also tries to send information about assoc ioctl to cfg80211 because "priv->assoc_request/priv->ibss_join_request" flag is on at that time. Fix the issue by updating request variable after assoc handling and modifying the variable check in mwifiex_cfg80211_results.

* mwifiex: fix missing tsf_val TLVBing Zhao2011-05-02
| | | | | | | | | | In mwifiex_cmd_append_tsf_tlv(), two tsf_val TLVs should be filled in the buffer and then sent to firmware. The missing first TLV for tsf_val is added back in this patch. Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mwifiex: optimize driver initialization codeAmitkumar Karwar2011-04-19
| | | | | | | | | | | | 1) removal of unnecessary mwifiex_device structure 2) avoid passing adapter pointer to mwifiex_init_sw() 3) remove local variable drv_mode_info in mwifiex_add_card() 4) type change in mwifiex_bss_attr to match mwifiex_private 5) removal of more wordy comments Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

* mwifiex: use IEEE80211_HT_CAP_ macros for 11n cap_infoMarc Yang2011-04-04
| | | | | | | | | | | | | | | | | | | | | The hw_dot_11n_dev_cap reported by firmware hw_spec has different format than the 11n capabilities. Hence a lot of SET_ and RESET_ bit operation macros were used to convert the dev_cap format to 11n capability format. However the locally defined 11n ht_cap macros are not necessary as we can use IEEE80211_HT_CAP_ macros directly. The 32-bit dev_cap bitmap is added as comment to explain the mapping between firmware and 11n spec. Some unused macros and unnecessary adapter variables are also removed.
