AR9300 will be the first device supported of the AR9003 family. AR9300 1.0 hardware exists but it is not going to be sold anywhere so we completely skip its support. Signed-off-by:

ath9k supports the AR5008, AR9001 and AR9002 family of Atheros chipsets, all 802.11n. The new breed of 802.11n chips, the AR9003 family will be supported as well soon. To help with its support we're going to add a few callbacks for hardware routines which differ considerably instead of adding branch checks for the revision at runtime. Signed-off-by:

Davinci platforms apparently need more time in-between helper firmware blocks. Even though this is an increased delay, we only take this hit once at initialization time. Signed-off-by:

wl1251 is embedded chip that can be connected using SDIO bus, and is not an actual SDIO card. For this reason there is a need to pass some board specific data, like 'EEPROM is attached' flag or power control callback. However currently there is no way to pass this data through SDIO subsystem, so this patch registers dummy platform_device to allow that, until we have a better solution to this. Signed-off-by:

rt2800pci used the callback write_tx_desc to write the tx descriptor but also to update the txwi which is part of the dma mapped skb. Since the memory was already DMA mapped _before_ the call to write_tx_desc the device didn't get the txwi data at all or only sporadically. The call order is basically as follows (from rt2x00queue.c): 1) write_tx_data 2) rt2x00queue_map_txskb 3) write_tx_desc Hence, we shouldn't touch the skb in write_tx_desc anymore. To fix this issue create a new rt2800pci_write_tx_data callback and use it for updating the txwi _before_ the memory gets DMA mapped. The tx descriptor is still written (as before) in write_tx_desc. This patch allows basic TX on an rt305x soc device but I'm pretty sure that it will fix pci based cards as well. I can associate just fine with an AP now but I wasn't able to get a wpa secured connection working yet. Signed-off-by:

In a scenario, where a cfg80211 driver (station mode) does not send assoc request and assoc response IEs in cfg80211_connect_result after a successful association to an AP, cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE to the user space application with NULL data. This can cause an issue at the event recipient. An example of this is when cfg80211 sends IWEVASSOCREQIE and IWEVASSOCRESPIE events with NULL event body to wpa_supplicant. The wpa_supplicant overwrites the assoc request and assoc response IEs for this station with NULL data. If the association is WPA/WPA2, the wpa_supplicant is not able to generate EAPOL handshake messages, since the IEs are NULL. With the patch, req_ie and resp_ie will be NULL by avoiding the assignment if the driver has not sent the IEs to cfg80211. The event sending code sends the events only if resp_ie and req_ie are not NULL. This will ensure that the events are not sent with NULL event body. Signed-off-by:

This patch fixes two warnings below after unplugging ar9271 usb device: -one is a kernel warning[1] -another is a lockdep warning[2] The root reason is that __skb_queue_purge can't be executed in hardirq context, so the patch forks ath9k_skb_queue_purge(ath9k version of _skb_queue_purge), which frees skb with dev_kfree_skb_any which can be run in hardirq context safely, then prevent the lockdep warning and kernel warning after unplugging ar9271 usb device.

We get RXORN interrupts when all receive buffers are full. This is not necessarily a fatal situation. It can also happen when the bus is busy or the CPU is not fast enough to process all frames. Older chipsets apparently need a reset to come out of this situration, but on newer chips we can treat RXORN like RX, as going thru a full reset does more harm than good, there. The exact chip revisions which need a reset are unknown - this guess AR5K_SREV_AR5212 ("venice") is copied from the HAL. Inspired by openwrt 413-rxorn.patch: "treat rxorn like rx, reset after rxorn seems to do more harm than good" Signed-off-by:Bruno Randolf <br1@einfach.org> Signed-off-by:

There was a confusion in the usage of the bits AR5K_STA_ID1_ACKCTS_6MB and AR5K_STA_ID1_BASE_RATE_11B. If they are set (1), we will get lower bitrates for ACK and CTS. Therefore ath5k_hw_set_ack_bitrate_high(ah, false) actually resulted in high bitrates, which i think is what we want anyways. Cleared the confusion and added some documentation. Signed-off-by:

Add RT3390 specific register initializations to rt2x00, based on the latest Ralink rt3390 vendor driver. Untested as I don't actually own an RT3390 based device, but given experiences on rt3070/rt3071 very hopeful that this will actually work.. Signed-off-by:

Add RT3071 specific register initializations to rt2x00, based on the latest Ralink rt3070 vendor driver. With this patch my RT3071 based devices start showing a sign of life. Signed-off-by:

rt2x00 had preliminary support for RT3070 based devices, but the support was incomplete. Update the RT3070 register initialization to be similar to the latest Ralink vendor driver. With this patch my rt3070 based devices start showing a sign of life. Signed-off-by:

Align the rt2800 register initializations with the latest versions of the Ralink vendor driver. This patch is also preparation for the addition of support for RT3070 / RT3071 / RT3090 / RT3390 based devices. Signed-off-by:

The rt2800 version constants are inconsistent, and the version number don't mean a lot of things anyway. Refactor the constants to have some more meaningful names, and introduce and use some new helpers to check these chipset revisions. At the same time rename to revision, as they are more revision numbers rather than version numbers. Signed-off-by:

It seems that the distinction between RF channel switch method is solely based on the RF chipset that is used. Refactor the channel switch decision to just take the RF chipset into account, thereby greatly simplifying the check. Signed-off-by:

This patch fixes an old problem, which - under certain circumstances - could cause the device to become unresponsive. most of p54pci's rx-ring management is implemented in just two distinct standalone functions. p54p_check_rx_ring takes care of processing incoming data, while p54p_refill_rx_ring tries to replenish all depleted communication buffers. This has always worked fine on my fast machine, but now I know there is a hidden race... The most likely candidate here is ring_control->device_idx. Quintin Pitts had already analyzed the culprit and posted a patch back in Oct 2009. But sadly, no one's picked up on this. ( https://patchwork.kernel.org/patch/53079/ [2 & 3] ). This patch does the same way, except that it also prioritize rx data processing, simply because tx routines *can* wait. Reported-by:

We used to free all the Tx queues memory when interface is brought down and reallocate them again in interface up. This requires order-4 allocation for txq->cmd[]. In situations like s2ram, this usually leads to allocation failure in the memory subsystem. The patch fixed this problem by allocating the Tx queues memory only at the first time. Later iwl_down/iwl_up only initialize but don't free and reallocate them. The memory is freed at the device removal time. BTW, we have already done this for the Rx queue.
