mwifiex: use bss_type and bss_num to retrieve priv

2012-01-24T19:21:12+00:00

Current implementation, for retrieving priv from adapter,
uses bss_index. In multi interface environment supporting
different types, bss_index may not be unique.

Use bss_type along with bss_num to retrieve the priv.
bss_index is removed with this change.

mwifiex: use separate wait condition for each command node

2011-10-14T18:48:20+00:00

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.

mwifiex: remove mwifiex_recv_complete function

2011-05-12T18:10:50+00:00

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.

mwifiex: remove redundant local variables and comments

2011-04-19T19:38:04+00:00

Remove some local variables (mainly function return values)
that are used only once. Also, one dummy function and some
wordy comments are removed.

mwifiex: cleanup ioctl wait queue and abstraction layer

2011-04-14T19:35:11+00:00

1) remove mwifiex_alloc_fill_wait_queue() and
mwifiex_request_ioctl()
2) avoid dynamic allocation of wait queue
3) remove unnecessary mwifiex_error_code macros that
were used mainly by the wait queue status code
4) remove some abstraction functions
5) split mwifiex_prepare_cmd() to mwifiex_send_cmd_async()
and mwifiex_send_sync() to handle asynchronous and
synchronous commands respectively
