The station didn't get into psm after recovery, because psm was configured before sta role was started. Move wl1271_ps_set_mode() to be executed only after the role was started. Signed-off-by:

In some corner cases, (invalid) 11g rates were used while working on 11a band. Take care of it by initializing rate_set according to the configured band. Signed-off-by:

There was a check preventing 127x devices from using the 11a band when operating as AP. Since we now support this functionality, remove the check. With this patch, a 11a AP starts ok on 127x cards. 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:

Only increment the queue count after actually queuing the skb. This avoids a spurious increment is case of dropped packets. Also move the Tx-watermark checking code after the packet is enqueued. This makes the count more accurate - it includes the just-queued packet. Signed-off-by:

Don't pollute the queues with Tx directed to invalid stations. This can happen during recovery. Signed-off-by:

This adjusts FW TX block allocation for connected stations in PS. Firmware congestion is measured in allocated packets instead of blocks. Allow a link in PS to queue up to 2 packets to the FW. Signed-off-by:

Sometimes the fw doesn't send the DISCONNECT_EVENT_COMPLETE_ID on station role stop, so don't wait for it. Signed-off-by:

When the FW Tx released blocks counter wraps around, we should correct our calculation of released blocks. Otherwise we add a large negative figure to our driver freed blocks counter 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:

Track the number of freed packets in each AC when receiving an interrupt from the FW. This paves the way for tracking allocated packets per AC. Signed-off-by:

When wep key was removed after disconnection, sta_hlid was invalid, and it resulted in a fw crash. Signed-off-by:
-
Eliad Peller authored
when the key was recorded, wl->ap_bcast_hlid was invalid (since the role wasn't started), so when configuring the key we need to use the current ap_bcast_hlid. Signed-off-by:

Unconditionally configure HT rate support to the FW on all ACs when starting the AP. When 11n support is disabled by usermode (hostapd), each STA joining the AP will appear as a non-HT STA. This will stop us from accidentally transmitting using MCS rates. Signed-off-by:

Start IBSS role when the interface type is IBSS. As with sta role, use the dev role until the role is started. Signed-off-by:

Eliad Peller authored
Add wl12xx_cmd_role_start_ibss() implementation and defintion. This function is used in order to start the IBSS role. Stopping the IBSS is done by using the same api as stop STA, so there is no need for a separate function. Signed-off-by:

If hlid was already removed, there is no need to remove its key (it might cause a fw crash, as the key is invalid). Signed-off-by:

After adding a station, call wl12xx_cmd_set_peer_state(). This is required for 11n support. Change wl12xx_cmd_set_peer_state() prototype to get hlid as param. Signed-off-by:

Incorporate interface changes for HT support. Add ba_bitmap field to the wl1271_link struct, to indicate activate RX BA sessions (for AP mode). Signed-off-by:

Using hlid=0 in AP mode is a bug. Dynamically allocate HLIDs. Set the "first sta hlid" as 3. This will have to be changed when multiple vifs will be supported. 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:

Use ACX_BEACON_FILTER_OPT for both station and ap roles (use the generic wl1271_acx_beacon_filter_opt() instead of wl1271_acx_set_ap_beacon_filter() ). Signed-off-by:

The max template size was increased in the new fw. However, we should use the max size only when needed, as it consumes some of the chip's memory. Thus, by default initialize the templates to the default size. Initialize to the maximum size only when required. Use WL1271_CMD_TEMPL_DFLT_SIZE instead of some of the predefined structs, as some of them didn't account for additional IEs that might be added to the template. Delete structs defintions not used after these changes. Signed-off-by:

The device role is a special role used for rx and tx frames prior to association (as the STA role can get packets only from its associated bssid) Since this role is required for the sta association process, we enable it when a new sta interface is created. Signed-off-by:

According to the new multi-role flow, we have to enable the role before using (starting) it, and disable it on cleanup (after it's no longer needed). 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:

Update the acx commands according to the new fw api (fw >= 6/7.3.0.0.75). The main change in most of the ACXs is the addition of a new role_id/link_id field, which is required for multi-role operation. Currently, we don't really support multi-role, as most of our data (inside wl) is global. As the current fw doesn't support concurrent roles yet, keep it this way and add wl->role_id and wl->sta_hlid to save the active role/link. Signed-off-by:
