With the new EDMA descriptor format, a single descriptor can contain up to four buffer pointers. By splitting the buffer into two parts, we can let the hardware add the padding internally instead of using memmove on the skb data. Signed-off-by:

The only flag that needs to be set when ath_tx_rc_status is called with rc_update == false is the IEEE80211_TX_STAT_TX_FILTERED flag. All other data is ignored in that case. This flag can be set from ath_tx_complete_buf instead, so that we can drop a few redundant calls to ath_tx_rc_status and remove the rc_update function parameter Signed-off-by:

With the new API, tx descriptors can be written in one single pass instead of having to re-read and rewrite fields from multiple places. This makes the code easier to read and also slightly improves performance on embedded MIPS hardware. Signed-off-by:

Instead of using lots of different functions with long argument lists, pull all the necessary information from one struct. This makes the code easier to read and eliminates the need for copying data between multiple linked descriptors. Signed-off-by:

During a reset, rx buffers are flushed after rx has been disabled. To avoid race conditions, rx needs to stay disabled during the reset, so avoid any calls to ath9k_hw_rxena in that case. Signed-off-by:

When starting the AP beacon timer, it assumes that the TSF has recently been cleared. Set the SC_OP_TSF_RESET flag to ensure that this is always the case. Signed-off-by:

AR9003 seems to have issues sometimes with fast channel change in 5GHz and this case is handled specifically for AR9280 by doing a full reset. Let's do a full reset for 5GHz channles of AR9380 & for all channels of AR9280 pci chips. Signed-off-by:

Normally, the v9 firmware will be loaded if it's available. However, on OLPC XO-1 machines, the olpc-specific firmware supports extra functionality. This makes the libertas driver attempt to load the custom firmware first if the machine is an OLPC machine; if that fails (or it's not an OLPC machine), fall back to attempting to load the other firmwares. usb8388_olpc.bin is currently found in the linux-firmware repository.

If a STA is not known by the hw (i.e. has no WCID assigned) don't allow aggregation since this might mess up tx status reports and we won't be able to distinguish the reports of multiple WCID-less STAs. Signed-off-by:
-
Helmut Schaa authored
This allows us to assign a WCID to each STA even for STAs without crypto key. To achieve this search for an unused WCID in the HW WCID table and assign it to the according STA. When configuring a pairwise key for this STA we don't need to write the MAC address and BSSIDX anymore but just update the crypto related fields in the WCID_ATTR table. This has two advantages: 1) Setting a new key for an already available STA (PTK rekeying) is slightly less expensive and should improve performance in situations where a lot of rekeying happens (e.g. a huge number of stations and/or a small rekeying interval) 2) The TXWI now gets a WCID assigned for unencrypted frames which will be reflected in the corresponding tx status report. This should make tx status reports in unencrypted AP mode more reliable as we can distinguish between multiple key-less STAs. Signed-off-by:

Helmut Schaa authored
When sending an unencrypted frame to a STA the driver might want to pass a suitable WCID since we don't have a key index to allow tx status reports to get properly assigned to the correct STA. Signed-off-by:

Helmut Schaa authored
When a WCID was already assigned to a STA the key configuration functions need to use the same WCID for configuring the keys. Hence, add the WCID to the crypo configuration structure. Signed-off-by:

This implements a basic sta_add and sta_remove callback. Introduce a new structure rt2x00_sta and ask mac80211 to allocate it as private part of its ieee80211_sta. rt2x00_sta only contains the WCID for now. The sta_add callback allows the driver to assign a WCID to a station that is currently being added. The same wcid is also passed to the sta_remove callback one mac80211 removes this STA.

The hw.conf.channel value is not updated properly for drivers that support HW channel switch. Since the switch is done entirely by the driver and we don't call ieee80211_hw_config(), this value remains untouched. This patch fixes that by setting the new channel directly in ieee80211_chswitch_work(). Signed-off-by:

Per sec 7.1.3.5 of draft 12.0 of 802.11s, mesh frames indicate the presence of the mesh control header in their QoS header. Signed-off-by:
-
Javier Cardona authored
In order to support QoS in mesh, we need to assign queue mapping only after the next hop has been resolved, both for forwarded and locally originated frames. Also, now that this is fixed, remove the XXX comment in ieee80211_select_queue(). Also, V-Shy Ho reported that the queue mapping was not being applied to the forwarded frame (fwd_skb instead of skb). Fixed that as well. Signed-off-by:

Reading the TX desciptor words from coherent memory is always uncached and potentially slow. Hence, don't read the TX descriptor prior to writing it since we update all fields anyway. Signed-off-by:

rt2800 devices are not capable of configuring arbitrary LED on/off periods. The LED_CFG register fields ON_PERIOD and OFF_PERIOD are only used by the hw when the LED mode is set to "blink upon TX". Hence, remove the blink callback. This will result in software emulation for LED blinking. Signed-off-by:
