wcn36xx's Issues

support interface combination (managed and AP) ?

Latency issue

Hi,

first of all i want to say thank you for your excellent work on this driver!

I'm experiencing latency issues, for instance a ping on my WLAN-Router takes 200 ms to 1000 ms. First I strictly followed your wiki to build the module and tested it on CM-10.1 and CM-10.2 using a Nexus 4. After that I tried different kernel configurations and WCNSS_qcom_cfg.ini modifications, with the aim to disable filtering and debug related configurations. As a result this had no impact on the latency so I now wonder if this is a known issue and if there exists a possible solution for it. This won't happen with Prima-WLAN.

Regards,
Markus

Squeeze all responses into one in hal.h

e.g. instead of struct set_tx_pwr_rsp_msg(https://github.com/KrasnikovEugene/wcn36xx/blob/master/hal.h#L3533) general structure must be used with only one field 'status' like struct wcn36xx_fw_msg_status_rsp https://github.com/KrasnikovEugene/wcn36xx/blob/master/smd.h#L135

Add encryption information to bss_conf

After discussing with johaness it will be good to add encryption information to bss_conf so that wcn36xx can call config_bss from bss_info_changed with encryption type.

WCN36XX_HAL_STOP_RSP does not have a break

check if this is correct

add copyright

"Copyright (c) 4-digit year, Company or Person's Name"

Rework wcn36xx_smd_notify

Now in function wcn36xx_smd_notify we queue smd_work but do we really need that? May be we can handle SMD responses in the same context as wcn36xx_smd_notify. Double check that and probably can get rid of wcn36xx_wq work queue.

Crash in wcn36xx_dxe_tx_frame

Tried to run iperf full throttle and crash occurred. All logs were disabled.
Iperf line:
iperf -c 192.168.0.199 -u -i5 -t3600 -b70M

ANT+ Support

Does the driver support ANT+

wcn36xx_hal_mac_mgmt_hdr can be reused from mac80211

https://github.com/KrasnikovEugene/wcn36xx/blob/master/hal.h#L825

Remove endian ifdef from hal.h

https://github.com/KrasnikovEugene/wcn36xx/blob/master/hal.h#L783

Set correct op_rate_mode

https://github.com/KrasnikovEugene/wcn36xx/blob/master/main.c#L449
Must be set to STA_11b if connecting to b only AP.

add HAS_DMA to kconfig

wcn36xx must depend on HAS_DMA

wcn36xx: ERROR Can not enter BMPS!

reason?

Support monitor mode

Hi,
is it possible support monitor mode? :)

Set correct output power

join/config_bss and other SMD commands do not set correct max_tx_power.

Add WEP encryption support

WEP is not supported so far.

Acknowledge NULL frame immediately during scanning

Step by step

1. Start scan
2. Send NULL frame with ACK request
3. Finish scan
4. WCN36XX_HAL_OTA_TX_COMPL_IND arrives. Tx complete must arrive just after bullet 2 otherwise queues are blocked.

Promisuous mode

Dr sir,
Does the driver support promisuous mode？And How can i replace the default wlan driver in nexus4？
I run tcpdump in nexus with default driver. Although dmesg shows that wlan0 enter promisuous mode，no packet between other client in Ap can be capture. I guess it is the driver does not support the modr. SO How about yours?thx

rename for wcn36xx enum pe_stats_mask check

enum pe_stats_mask should be renamed https://github.com/KrasnikovEugene/wcn36xx/blob/master/hal.h#L593

wcn36xx must check HW version in runtime

wcn36xx must check HW version in runtime and change API version in runtime if hw is 3660 or 3680.

Rework DXE mask

Duplicated enum

/* Interrupt control channel mask */

define WCN36XX_INT_MASK_CHAN_TX_L 0x00000001

define WCN36XX_INT_MASK_CHAN_RX_L 0x00000002

define WCN36XX_INT_MASK_CHAN_RX_H 0x00000008

define WCN36XX_INT_MASK_CHAN_TX_H 0x00000010

is the same as

define WCN36XX_DXE_INT_CH4_MASK 0x00000010

define WCN36XX_DXE_INT_CH3_MASK 0x00000008

/* #define WCN36XX_DXE_INT_CH2_MASK 0x00000004 */

define WCN36XX_DXE_INT_CH1_MASK 0x00000002

define WCN36XX_DXE_INT_CH0_MASK 0x00000001

Send TX data frames over low prio dxe ch

Currently all data frames are sent over High prio channel but must be sent ove Low prio channel/ring buffer.
