* | ath5k: Stop PCU on resetNick Kossifidis2010-11-30
| | | | | | | | | | | | | | | | | | | | | | * Stop PCU receive logic (DRU) durring reset We need to be sure pcu is not active when trying to stop rx dma right now this is done on ath5k_reset (base.c) but later we are going to clean it up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * No functional changes * Clean up reset: Introduce init functions for each unit and call them instead of having everything inside ath5k_hw_reset (it's just c/p for now so nothing changes except calling order -I tested it with various cards and it's ok-) * Further cleanups: ofdm_timings belongs to phy.c rate_duration belongs to pcu.c clock functions are general and belong to reset.c (more to follow) * Reorder functions for better organization: We start with helpers and other functions follow in categories, init functions are last Signed-off-by: Nick Kossifidis <mickflemm@gmail.com> Signed-off-by: John W.

It has been suggested that there is hardware which can set the descriptors done bit before it reads ds_link and moves on to the next descriptor. While the documentation says this is not true for newer chipsets (the descriptor contents are copied to some internal memory), we don't know about older hardware. To be safe, we always keep the last descriptor in the queue, and avoid dangling TXDP pointers. Unfortunately this does not fully resolve the problem - queues still get stuck!

The way we set up our queues matches the mac80211 queue priority 1:1, so we don't have to do any mapping for queue numbers. Every queue uses 50 of the total 200 available transmit buffers, so the DMA memory usage does not increase with this patch, but it might be good to fine-tune the number of buffers per queue later (depending on the CPU speed and load, and the speed of the medium access, it might not be big enough).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change reorganizes the main ath5k file in order to re-group related functions and remove most of the forward declarations (from 61 down to 3). This is, unfortunately, a lot of churn, but there should be no functional changes.

This fixes problems with HW encryption in AP mode, which was broken in the ath5k implementation. Before (with the ath5k implementation) only one client could connect to the AP using HW encryption and WPA. When a second client connected, the first client was not able to send/receive any more packets. Because of the problems with HW encryption, software encryption was always used in AP mode, which resulted in a high CPU load (and/or low thruput) on embedded devices. Instead of trying to fix the implementation in ath5k it makes more sense to share the code with ath9k. This also enables HW encryption for AP mode again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the symbol offset is 46, it will be counted in both the third and fourth bytes of the mask, and in this case the shift will be negative which can pollute high order bits in the mask. This may negatively impact OFDM symbol detection. Signed-off-by: Bob Copeland <me@bobcopeland.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
