* wl1271: 11n Support, functionality and configuration abilityShahar Levi2010-11-154-18/+105
| | | | | | | | | | Add 11n ability in scan, connection and using MCS rates. The configuration is temporary due to the code incomplete and still in testing process. That plans to be remove in the future. Signed-off-by: Shahar Levi <shahar_levi@ti.com> Reviewed-by: Luciano Coelho <luciano.coelho@nokia.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>

* wl1271: Fix TX queue low watermark handlingIdo Yariv2010-11-151-13/+22
| | | | | | | | | | | | | | | | | | The number of entries in the TX queue is compared to the low watermark value each time TX completion interrupts are handled. However, the fact that a TX completion arrived does not necessarily mean there are any less skbs in the TX queue. In addition, a TX completion interrupt does not necessarily mean that there are any new available TX blocks. Thus, queuing TX work when the low watermark is reached might not be needed. Fix this by moving the low watermark handling to the TX work function, and avoid queuing TX work in this case.

* wl1271: Allocate TX descriptors more efficientlyIdo Yariv2010-11-153-16/+24
| | | | | | | | | | | | On each TX descriptor allocation, a free entry is found by traversing the TX descriptors array. Improve this by holding a bitmap of all TX descriptors, and using efficient bit operations to search for free entries.

* wl1271: Fix TX starvationIdo Yariv2010-11-154-8/+27
| | | | | | | | | | | | | | | While wl1271_irq_work handles RX directly (by calling wl1271_rx), a different work is scheduled for transmitting packets. The IRQ work might handle more than one interrupt during a single call, including multiple TX completion interrupts. This might starve TX, since no packets are transmitted until all interrupts are handled. Fix this by calling the TX work function directly, instead of deferring it.

* wl1271: TX aggregation optimizationIdo Yariv2010-11-151-8/+19
| | | | | | | | | | | | | | In case the aggregation buffer is too small to hold all available packets, the buffer is transferred to the FW and no more packets are aggregated. Although there may be enough available TX blocks, no additional packets will be handled by the current TX work. Fix this by flushing the aggregation buffer when it's full, and continue transferring packets as long as there are enough available TX blocks.

To make it easier to develop wl1271 features move wl1251 to it's own directory, drivers/net/wireless/wl1251. There are no functional changes, only moving of files. One regression is that Kconfig won't be updated automatically and user needs to enable wl1251 manually with an older config file. Signed-off-by: Kalle Valo <kvalo@adurom.com> Signed-off-by: John W.

| | | * wl1271: remove useless 11a check when scanningLuciano Coelho2010-09-281-4/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code was a leftover of the previous scanning mechanism. The if is totally unnecessary, since both branches do the same thing.

This makes it possible for ieee80211_scan_complete to be called twice in some scenarios, as the scan completion event from the firmware may be processed while the mutex is unlocked. To fix the issue, move the ieee80211_scan_complete call last in the function. This is generally safer, but there still may be issues is functions calling the scan state machine rely on states checked before the unlocking of the global mutex. (forward ported from 2.6.32 -- this is not strictly needed anymore, because the mutex doesn't need to be unlocked anymore, but I'm applying this change anyway, so that the call to ieee80211_scan_complete is in the same place) Signed-off-by: Juuso Oikarinen <juuso.oikarinen@nokia.com> Reviewed-by: Saravanan Dhanabal <ext-saravanan.dhanabal@nokia.com> Signed-off-by: Luciano Coelho <luciano.coelho@nokia.com>
