wifi: wilc1000: fix DMA on stack objects

2022-08-30T16:36:29Z

Sometimes 'wilc_sdio_cmd53' is called with addresses pointing to an object on the stack. Use dynamically allocated memory for cmd53 instead of stack address which is not DMA'able.

wifi: wilc1000: use existing iftype variable to store the interface type

2022-07-27T12:58:11Z

For consistency, use an existing 'iftype' element which was already having the interface type. Replace 'mode' with 'iftype' as it was used for the same purpose. Signed-off-by: Ajay Singh Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220720160302.231516-8-ajay.kathat@microchip.com

wifi: wilc1000: add IGTK support

2022-05-30T11:18:00Z

Add support to handle IGTK keys which are required for MFP to FW. Index ID 4 and 5 are used to store the IGTK key. Signed-off-by: Ajay Singh Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220524120606.9675-4-ajay.kathat@microchip.com

wifi: wilc1000: add WPA3 SAE support

2022-05-30T11:18:00Z

Enable SAE authentication for AP and STA mode. In STA mode, allow the driver to pass the auth frames which are received from firmware to userspace application(hostapd) so that SAE authentication is offloaded to userspace.

wifi: wilc1000: remove WEP security support

2022-05-30T11:18:00Z

Deprecated WEP security for WILC driver as well as in firmware from 15.6 FW release onwards. After WEP security removal, freeup some codespace which helped to add new features like WPA3 etc. Signed-off-by: Ajay Singh Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20220524120606.9675-2-ajay.kathat@microchip.com

wilc1000: Convert static "chipid" variable to device-local variable

wilc1000: Improve WILC TX performance when power_save is off

2021-12-16T08:30:21Z

The wakeup and sleep commands need to be sent to the WILC chip only when it is in power save mode (PSM, as controlled by "iw dev wlan0 set power_save on/off"). The commands are relatively costly, so it pays to skip them when possible. iperf3 without this patch (no significant different with PSM on/off): TX 0.00-120.01 sec 140 MBytes 9.82 Mbits/sec RX 0.00-120.69 sec 283 MBytes 19.6 Mbits/sec with this patch applied: PSM off (TX is 46% improved, RX slightly improved; may not be significant): TX 0.00-120.00 sec 206 MBytes 14.4 Mbits/sec RX 0.00-120.48 sec 322 MBytes 22.4 Mbits/sec PSM on (no significant change): TX 0.00-120.00 sec 140 MBytes 9.78 Mbits/sec RX 0.00-120.08 sec 257 MBytes 18.0 Mbits/sec Signed-off-by: David Mosberger-Tang Signed-off-by: Kalle Valo Link: https://lore.kernel.org/r/20211210203016.3680425-2-davidm@egauge.net

wilc1000: use eth_hw_addr_set()

2021-10-20T09:39:46Z

Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers.

wilc1000: configure registers to handle chip wakeup sequence

2021-09-21T15:08:15Z

Use the correct sequence to configure clockless registers for chip wake-up. The following sequence is expected from WILC chip for wakeup: - set wakeup bit in wakeup_reg register - after setting the wakeup bit, read back the clock status bit for wakeup complete. For SDIO/SPI modules, the wakeup sequence is the same except uses different register values so refactored the code to use common function for both SDIO/SPI bus.

wilc1000: move 'deinit_lock' lock init/destroy inside module probe

2021-09-21T15:08:14Z

Move initialization & deinitialization of 'deinit_lock' mutex lock inside wlan_init_locks() & wlan_deinit_locks() API's respectively alongside other locks. After the movement, the client count variable(client_count) which is used for lock init/deinit is removed.
