[PATCH 00/26] use unified firmware and add ops in cfg

[Glen Lee]

This patch series contains
* support suspend and resume functionality
* use a unified firmware for all mode of operations(station, ap, p2p)
* support Station/AP concurrency
* increase link speed
* add a cfg operation for adjusting the tx power
* fix bug on p2p, WEP security and chaning virtual interface

[PATCH 01/26] staging: wilc1000: fix bug when changing virtual interface

[Glen Lee]

This patch fixes a bug connection error when changing virtual interface to p2p.
Variable quit needs to be set 0 when wilc is reinitialized again.

Fixes : 67e2a07ed800 ("staging: wilc1000: move all of wilc_wlan_dev_t to struct wilc")

[PATCH 03/26] staging: wilc1000: support suspend/resume functionality

[Glen Lee]

wilc supports suspend/resume functionality. Introduce new sleep and wakeup
functions and remove old codes since that will be handled in the new functions.

[PATCH 10/26] staging: wilc1000: remove wilc_set_machw_change_vir_if

[Glen Lee]

wilc_set_machw_change_vir_if is not used anymore since we use one unified
firmware. Instead, wilc_set_operation_mode is called when wilc_mac_open to
let the wilc use the proper firmware. Remove wilc_set_machw_change_vir_if
and it's functions calls.
In the later patch, mac index will be passed to wilc device.

netdevice for each mode.
The get_if_handler is changed together. Remove invalid handle codes and
add mode condition to get netdevice for the mode.

[PATCH 12/26] staging: wilc1000: set proper bssid address

[Glen Lee]

This patch changes index 0 to index of vif which is currently beging used
because AP mode can run on any interface.

[PATCH 13/26] staging: wilc1000: change_virtual_intf: change codes for unified firmware

[Glen Lee]

In previous patch, we use unified firmware on wilc, which means we do not need
to download firmware again to change virtual interfaces.
There are a lot of codes to change interface and they are needless now, so
remove them except wilc_set_operation_mode function which change the mode and
wilc_set_power_mgmt which control power save.
There will be unused functions and they will be removed in later patch.

[PATCH 14/26] staging: wilc1000: call power save after changing mode

[Glen Lee]

host_int_set_power_mgmt should be called after changing operation mode to
work properly. Move the function below host_int_set_operation_mode.

[PATCH 15/26] staging: wilc1000: wilc_set_wfi_drv_handler: add mac index

[Glen Lee]

Firmware supports sta/ap concurrency so mac index will be passed to wilc.
Remove wilc_set_wfi_drv_handler in scan and connect functions, and call
the function in ndo_open which is wilc_mac_open.
WID_SET_DRV_HANDLER value has been changed as well.

[PATCH 25/26] staging: wilc1000: fix WEP security bug

[Glen Lee]

Station cannot connect to soft AP mode wilc when it is configured for WEP
security. This patch fixes it by setting the key index within the key value and
change the last else condition with DEFAULTKEY action case, and also do not use
WILC_WFI_wep_default index to set wep key id.

You can probably put these defines in a header somewhere instead of here.

Also, are these firmwares publicly available and have they been
submitted to linux-firmware?

Hi Julian,

It's better to define in header as you say. I'll do this later.

Not yet. We will patch new firmware as soon as possible.

s32 should almost always be changed to int.  Don't initialize variables
with bogus values.  GCC has a helper warning for uninitialized variables
and this disables GCC's uninitialized variable checking.

Casting an unsigned value from the user to signed seems like a recipe
