* wl1271: Increase connection reliabilityJuuso Oikarinen2010-09-28
| | | | | | | | | | | | This patch improves connection reliability by choosing the lowest basic rate for null-func frames (which increases their range, as the firmware does not do rate fall-back for null-func frames.) Also, increase the PSM entry retry-counter.

* wl1271: rewritten scanning codeLuciano Coelho2010-07-08
| | | | | | | | | | | | | | | | | | This patch is a complete rewrite of the scanning code. It now includes a state machine to scan all four possible sets of channels independently: 2.4GHz active, 2.4GHz passive, 5GHz active and 5GHz passive. The wl1271 firmware doesn't allow these sets to be mixed, so up to several scan commands have to be issued. This patch also allows scanning more than 24 channels per set, by breaking the sets into smaller parts if needed (the firmware can scan a maximum of 24 channels at a time). Previously, the scanning code was erroneously scanning all channels possible actively, not complying with the CRDA values. This is also fixed with this patch.

* wl1271: moved scan operations to a separate fileLuciano Coelho2010-07-08
| | | | | | | | | | | | | | The scanning code is going to get a bit more complex, with proper support for active/passive scans together with 2.4GHz and 5GHz. In the future, also a new type of scan (periodic scan) will be added. When all this is implemented, the code is going to be much more complex, so we'd better separate it into a separate file.

* wl1271: Work around AP's with broken ps-poll functionalityJuuso Oikarinen2010-07-08
| | | | | | | | | | | | | | | | | | | | | | | Some AP's (such as Zyxel Prestige 600) have totally broken ps-poll functionality. When powersave is enabled, these AP's will set the TIM bit for a STA in beacons, but when the STA responds with a ps-poll, the AP does not respond with data. The wl1271 firmware is able to send an indication to the host, when this problem occurs. This patch adds implementation, which temporarily disables power-save in response to this indication, allowing the AP to transmit whatever data it has buffered for the STA / whatever data is inbound at that time. This patch does not make these AP's work reliably in PSM, but improves the chances of inbound data getting through. The side effect of this patch is increased power consumption when using a faulty AP.

* wl1271: Fix PSM entryJuuso Oikarinen2010-02-19
| | | | | | | | | | | | | | Currently the PSM entry function assumes successful operation, and enables ELP, BET and beacon filtering right away. This is bad, because the PSM entry may fail due to environmental issues, which will cause the ELP, BET and beacon filtering to be illegally enabled (because FW remains in active state.) Fix this by enabling ELP, BET and beacon filtering only after successful entry, and by ensuring the firmware is in active mode after the failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were not handling endianess correctly. The wl1271 chip runs on little-endian values.

This chipset is designed for embedded devices, with good powersaving capabilities. The wl1271 chipset is the successor of wl1251 and supports the 802.11b/g/n standards, but currently this driver supports only b/g.
