Similar change as we already do for agn, need to avoid "Error setting Tx power (-5)" message when loading module. Signed-off-by:

Stanislaw Gruszka authored
Mac80211 can request for tx power and channel change in one ->config call. If that happens, *_send_tx_power functions will try to setup tx power for old channel, what can be not correct because we already change the band. I.e error "Failed to get channel info for channel 140 [0]", can be printed frequently when operating in software scanning mode. Signed-off-by:

genlmsg_cancel subtracts some constants from its second argument before calling nlmsg_cancel. nlmsg_cancel then calls nlmsg_trim on the same arguments. nlmsg_trim tests for NULL before doing any computation, but a NULL second argument to genlmsg_cancel is no longer NULL due to the initial subtraction. Nothing else happens in this execution, so the call to genlmsg_cancel is simply unnecessary in this case. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression data; @@ if (data == NULL) { ... * genlmsg_cancel(..., data); ... return ...; } // </smpl> Signed-off-by:

The register definition for retry configuration on AR5212 was wrong, and simply copied over from AR5210. Update the register definitions from the documentation. Let the short and long retries be configured from mac80211 and use the standard values of 7 and 4 by default. Also we need to make sure we don't export more retries than we are configured for to mac80211 (and the rate module) in hw->max_rate_tries. Also clean up the code by removing unused defines and variables and drop the different values for "station retries" - if these need to be different it can be handled tru ah_retry_long/short.

When this PLL hang issue is seen, both Rx and Tx fail to work. The sqsum_dvc needs to be below 2000 for a good chip. During this issue the sqsum_dvc value is beyond 80000 and only a full reset can solve this problem. Signed-off-by:

With this change, less CPU time is spent trying to look for consecutive pages for rx skbs. This also reduces the socket memory required for IP/UDP reassembly. Only two buffers per frame are supported. Frames spanning more buffers will be dropped, but the buffer size is enough to handle the required AMSDU size. Signed-off-by:

Sujith Manoharan authored
Commit "ath9k_hw: Relocate Opmode initialization" moved the opmode initialization before the STA_ID1 register was programmed with defaults. This changed the original behaviour because the re-programming code doesn't take into account the existing value in the register. Both ath9k and ath9k_htc were not affected by this change because the opmode is re-initialized after every reset, when RX is started. Revert to the original behavior, except keep it outside the REGWRITE block. This would help remove extraneous opmode calls in the driver core. Signed-off-by:

Some vendor specific cipher suites require non-zero key indexes for pairwise keys, but as of currently, the cfg80211 does not allow it. As validating they cipher parameters for vendor specific cipher suites is the job of the driver or hardware/firmware, change the cfg80211 to allow also non-zero pairwise key indexes for vendor specific ciphers.

This adds a few tracepoints to ath5k driver transmit and receive callbacks in order to record packet traffic. We record the entire packet in the trace buffer so that the data can be extracted with trace-cmd and external plugins. Compared to the previous debugging calls, this approach removes an out-of-line function call from the tx and rx paths in the compiled-in-but-disabled case, while improving the ability to process the logged data. A new option, CONFIG_ATH5K_TRACER, is added so that one may disable the tracepoints completely. Signed-off-by:

This enables 4.9GHz frequencies in ath5k if they are allowed as indicated by the regulatory domain code. Currently this is MKK9_MKKC (0xfe). Signed-off-by:
-
Bruno Randolf authored
This adds a helper function to ath/regd.c which can be asked if 4.9GHz channels are allowed for a given regulatory domain code. This keeps the knowledge of regdomains and defines like MKK9_MKKC in one place. I'm passing the regdomain code instead of the ath_regulatory structure because this needs to be called quite early in the driver inititalization where ath_regulatory is not available yet in ath5k. I'm using MKK9_MKKC only because this is the regdomain in the 802.11j enabled sample cards we got from our vendor. I found some hints in HAL code that this is used by Atheros to indicate 4.9GHz channels support and that there might be other domain codes as well, but as I don't have any documentation I'm just putting in what I need right now. It can be extended later. Signed-off-by:

Various places printing tx queue information used various different ways to get a tx queue index for printing statistics. Most of these ways were wrong. ATH_TXQ_AC_* cannot be used as an index for sc->tx.txq, because it is only used internally for queue assignment. One place used WME_AC_* as a queue index for sc->debug.stats.txstats, however this array uses the ath9k_hw queue number as well. Fix all of this by always using the ath9k_hw queue number as an index, and always looking it up by going through sc->tx.txq_map. Signed-off-by:

It does not make much sense to keep the current virtual wiphy implementation any longer - it adds significant complexity, has very few users and is still very experimental. At some point in time, it will be replaced by a proper implementation in mac80211. By making the code easier to read and maintain, removing virtual wiphy support helps with fixing the remaining driver issues and adding further improvements. Signed-off-by:

Instead of spreading ath_wake_mac80211_queue() calls over multiple places in the tx path that process the tx queue for completion, call it only where the pending frames counter gets decremented, eliminating some redundant checks. To prevent queue draining from waking the queues prematurely (e.g. during a hardware reset), reset the queue stop state when draining all queues, as the caller in main.c will run ieee80211_wake_queues(hw) anyway.

The commit 'ath9k: Add more information to debugfs xmit file.' added more debug counters to ath9k and also added some lines of code to ath9k_hw. Since ath9k_hw is also used by ath9k_htc, its code must not depend on ath9k data structures. In this case it was not fatal, but it's still wrong, so the code needs to be moved back to ath9k.
