Make sta use the global wl->links[hlid].tx_queue (by considering its links map) instead of wl->tx_queue, and then unify the tx and tx_reset flows for the various vifs. Signed-off-by:

Add wlvif->links_map bitmap to represent all the links allocated for this vif. AP vif also has a sta_hlid_map bitmap, which represents the links stations connected to it (sta_hlid_bitmap is a subset of wlvif->links_map, which itself is a subset of the global wl->links_map) Signed-off-by:

On roaming, the auth and assoc req are sent with the sta hlid. This is wrong, as the sta hlid is configured according to the old ap. Use the dev_hlid instead. Move the wl1271_tx_update_filters() call into wl1271_tx_get_hlid(), so wl->dev_hlid will be valid. Signed-off-by:

Reset the BA state of all connected stations and explicitly clear the Tx queues. The latter is needed for clearing dummy packets from tx_queue_count. Signed-off-by:

When operating as AP track the number of connected stations. When a single STA is connected don't regulate the PS status of the link. Since this is the only STA connected, there's no point holding space in FW for other links. This will speed up communications with a single connected STA in PSM. Signed-off-by:

Check a STA is associated before regulating its PS-status in mac80211. Should never happen, so warn as a precaution. [Small cosmetic change wrt Kalle Valo's comment. -- Luca] Signed-off-by:

Dummy packets are currently only sent on the system_hlid link. The system_hlid link should never be filtered for PS (as it is not a STA link). Even so, for correctness, don't indicate dummy packets up. The skb does not belong to mac80211 and as such does not contain a correct skb->cb. Signed-off-by:

Add tx_spare_blocks member to the wl1271 struct for more generic configuration of the amount of spare TX blocks that should be used. The default value is 1. In case GEM cipher is used by the STA, we need 2 spare TX blocks instead of just 1. Signed-off-by:

When selecting packets for transmission, prefer the ACs that are least occupied in the FW. When packets for multiple ACs are present in the FW, it decides which to transmit according to WMM QoS parameters. With these changes, lower priority ACs should not be starved when higher priority traffic is present. Signed-off-by:

The ROC command asks the fw stay on the channel of the given hlid. it currently has 2 primary functions: 1. Allow tx/rx from the device role. In order to tx/rx packets while the stations is not associated (e.g. auth req/resp), the device role has to be used, along with ROC on its link. Keep the logic similiar to the one used in dummy_join. However, since we can't scan while we ROC, we add CROC before starting a scan, and ROC again (if needed) on scan complete. 2. Keeping the antenna for a specific link. We ROC until the connection was completed (after EAPOLs exchange) in order to prevent BT coex operations from taking the antenna and failing the connection (after this stage, psm can be used). During association, we ROC on the station role, and then CROC the device role, thus assuring being ROC during all the connection process. Delete the WL1271_FLAG_JOINED flag, and use a roc bitmap to indicate what roles are currently ROCed. Add wl12xx_roc/croc functions in order to wrap the roc/croc commands while taking care of the roc bitmap. The current ROC/CROC state-machine is a bit complicated. In the future we'll probably want to use wpa_supplicant to control the ROC during connection. Signed-off-by:

Change the commands and events according to the new fw api (fw >= 6/7.3.0.0.75). The main change is the replacement of JOIN/DISCONNECT commands, with ROLE_START/ROLE_STOP commands. The use of these commands should be preceded by the ROLE_ENABLE command (allocating role resources), and followed by the ROLE_DISABLE command (freeing role resources). Signed-off-by:

Split tx_queue_count to count per-AC skb's queued, instead of relying on the skb-queue len. The skb queues used were only valid in STA-mode, as AP-mode uses per-link queues. This fixes a major regression in AP-mode, caused by the patch "wl12xx: implement Tx watermarks per AC". With that patch applied, we effectively had no regulation of Tx queues in AP-mode. Therefore a sustained high rate of Tx could cause exhaustion of the skb memory pool. Signed-off-by:

When operating with TKIP encryption, the function wl1271_tx_fill_hdr() relocates the 802.11 header to the start of the frame, and leaves room for the security header. Some functions in the Tx path rely on the location of the header, namely, for purposes of roaming in STA mode and connecting new stations in AP mode. Call these functions only after the header is relocated. Signed-off-by:

Do not reset the security sequence number when issuing a join command or interface is removed. Instead, reset the counter only during the unjoin command. Added the notion of counter wrap-around to the LSB number in wl1271_tx_complete_packet. Added post recovery padding to adjust for potential security number progress during the recovery process by the firmware and avoid potential interop issues in encrypted networks. Signed-off-by:

When resuming (after wowlan), we want the rx packets (which is usually the wake-up packet itself) to be passed to mac80211 only after the resume notifier was completed, and mac80211 is up and running (otherwise, the packets will be dropped). By enqueueing the netstack_work to a freezable workqueue, we can guarantee the rx processing to occur only after mac80211 was resumed. Signed-off-by:
