Macros CL_SNPRINTF and CL_PRINTF are always used in that order. The first formats info into a buffer, and the second dumps it with printk. As the debug system in rtlwifi has a macro that does this with a single call, it seems reasonable to use it instead. An additional benefit is that the debug level can be set when loading the driver used by the wifi device. Signed-off-by:

We have a logic in driver to delay or abort low priority scan to serve Tx traffic effectively. With scan channel gap support added, firmware now allows driver to send Tx data while scan operation is in progress. Hence low priority scan handling in driver is not required now. This patch removes related code. Signed-off-by:

With channel scan gap, FW comes back to connected channel after each single channel scan. So we can safely transfer data to FW during scan. FW would send this data once on connected channel. Signed-off-by:

With scan channel gap when any station/AP is active, FW comes back to connected channel for any pending data transfter after scanning each channel. We set scan channel gap TLV to FW in scan command when any of the interface is active. This enables scan channel gap in FW. Also when scan channel gap is enabled, we would scan maximum channels allowed by FW. Scan channel gap is supported only on FW with V15 FW API. Signed-off-by:

It was observed that station would sent probe request even when scan type has been set as passive during iw scan. This was happening because driver sets passive scan type only when channel has IEEE80211_CHAN_NO_IR flag set. Along with this, add condition to check if no ssids are specified in scan request so as to mark such scan request passive. Signed-off-by:

When aggregation port limit is reached, we stop aggregation and the data is sent to firmware. It is observed that one less packet than the port limit is aggregated in this case. ex. 15 instead of 16. The reason is we have redundant port limit checks before current packet is added to aggregation buffer. The issue is fixed by removing these checks. We already have necessary check in precopy current buffer handling. Signed-off-by:

When assocaiting to an AP , mwifiex set supported data rates based on target AP's capability. For 5G AP(11a mode), a/n/ac mode would possibly be set. However, for some chips which dont support 11AC mode current config_bands will be used instead. For example, if we join an IBSS in 11b mode ,adapter->config_bands will be set to 1(11b mode). Then we leave IBSS ,and try to connect 5G a/n mode AP. At this time , only 11b mode data rates will be supported in assoc request , which result in assoc failure with reason code 18: Association denied due to requesting station not supporting all rates. This patch fix such a cornel case, by adding additional check for current chip's 11ac capability. Reported-by:

There was an issue with internal scan during association wherein we would complete internal scan on first scan command response. This would cause association failure if AP is not found in first scan response e.g. APs from A band. This patch fixes this issue by completing internal scan only when all scan commands from scan pending queue and command pending queue are sent to FW and response to last scan command is received.

If we dont set FW API info here, for older FW releases where FW API is not available in GET_HW_SPEC, API version would remain 0. This may cause issues with 11ac if older FW is used with newer driver. Signed-off-by:

When interfaces of different types are present in a context and an offchannel request is received on a STA interface, we end up trying to process beacons received when we are offchannel. This hits the below warning since offchannel will not have proper beacon parameters.
