* mwifiex: remove unnecessary free_priv handlerAmitkumar Karwar2011-11-11
| | | | | | | | | | | | | | | | | | Cfg80211 stack allocates private area for driver use in struct cfg80211_bss. It will be freed by stack in bss_release(). Driver don't need to worry about it. In mwifiex driver, we use the private area just to store band information(u8). We don't allocate memory explicitly and store it's pointer in bss->priv. Hence we don't have any cleanup work to do in free_priv handler. Currently we try to free the allocated private area in free_priv handler which is not correct. This patch removes unnecessary free_priv handler. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

| * mwifiex: use separate wait condition for each command nodeAmitkumar Karwar2011-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently global wait condition (adapter->cmd_wait_q.condition) is used while sending synchronous commands to FW. When two threads enter in mwifiex_send_cmd_sync() routine at the same time, both the threads wait for their command responses. Since wait condition is same for both, they wake up simultaneously after getting response of 1st command. After this when a thread is waiting for command response of 3rd command, it wakes up after getting response of 2nd command and so on. Therefore we don't wait for the response of last command(0xaa) during unload. Hence while next time loading the driver command time out is seen for INIT command. This problem is resolved by having separate wait condition flag for each command(except scan command). Since scan command is treated differently (by maintaining scan pending q etc.), newly defined flag (scan_wait_q_woken) is used as a scan wait condition.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In recent commit "mwifiex: use cfg80211 dynamic scan..." (7c6fa2a843..) scan table handling in driver is removed to make use of cfg80211 dynamic scan table. Now driver sends beacon buffers found in scanning directly to stack and parse the buffer for requested BSS only during association. Beacon buffer doesn't contain bss band information. Driver gets it from firmware in separate tlv (chan_band_tlv). Currently since we don't inform stack about bss bandinfo, there is an issue with 5GHz association. Use "priv" field of struct cfg80211_bss to store bandinfo. This fixes 5GHz association issue.

Currently while preparing scan channel list for firmware Null entries are created for disabled channels. The routine which retrieves this list ignores channels after Null entry. Hence sometimes driver doesn't scan the channel of requested AP and association fails. The issue is fixed by avoiding those NULL entries.

* mwifiex: 4-byte alignment in mwifiex_process_sta_txpd()Yogesh Ashok Powar2011-07-08
| | | | | | | | | | | | | | | | | | | 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.

* mwifiex: fix minor issue in debugfs command 'info'Amitkumar Karwar2011-07-08
| | | | | | | | | | | | | | | | Debugfs command 'info' shows wrong interface type. The regression occurred due to commit eecd8250e (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.
