We have a new STA cmd as part of the new MLD API. There are some parts of sending the STA cmd which are common to both the old and the new one. Put this parts in functions which will later be used to send the new STA cmd. Signed-off-by:

As the new MLD API is introduced, we have a new enumeration for the different station types. Since struct iwl_mvm_sta's sta_type field will be in use for both new and old API, change its type to a unified one, so it can hold both. Signed-off-by:

This function sends the STA_HE_CTXT_CMD, which won't be used in the new MLD API. Instead, a part of the fields of this command will be in the new STA cmd. Put the parts that are common to both commands in functions, which will later be used in sending the new STA cmd. Signed-off-by:

We used to send a MAC CTXT cmd to ask the FW to not pass MCAST frames if we're associated but not authorized, because we don't have the keys in that stage, and after authorization - we sent the cmd again to ask the FW to pass MCAST, as we have the keys now. The patch linked below was changing this strategy to always allow MCAST frames, and if we're not authorized - the driver will drop them. But we're still sending the MAC CTXT cmd after deaouthorization even though we don't tell the FW to not pass MCAST frames anymore. Basically we don't tell the FW anything new with this cmd. Fix this by not sending MAC CTXT command after deauthorization. For authorization we're sending the cmd to configure other changes too, so keep it. Signed-off-by:

iwl_mvm_get_sync_time() reads the gp2 from the device and then reads the system clock. Since the two reads are not done atomically, unexpected delays may happen between the two reads (e.g. context switch) which make it inaccurate. In order to improve the accuracy of the cross timestamp, call iwl_mvm_get_sync_time() multiple times in a loop and take the result in which the difference between the two clock is the smallest.

Implement the following PHC operations: 1. adjtime - for adding an offset to the PHC clock time. 2. adjfine - for adjusting the PHC clock frequency. 3. gettime64 - for getting the PHC clock time. This function returns the time as adjusted by adjtime and adjfine. The adjusted time will also be used for time sync frames timestamping. Signed-off-by:

For TM/FTM frames, report the hardware timestamps reported by the fw as part of the RX/TX status. Since the fw reports the timestamps in a dedicated notification (and not as part of the RX/TX status), hold the frame until the fw timestamps notification is received. Timestamping is enabled when a station is connected and disabled when disconnected. For AP interface, only the first station will have timestamping enabled since the fw only supports timestamping for one peer. Signed-off-by:

If the firmware supports reading synced GP2/ATRB timestamps, read the synced timestamps from firmware instead of reading the GP2 register and the system time separately. Reading the synced time from firmware should be more accurate. Signed-off-by:

Add support to enable/disable PHC clock. The PHC clock includes support for fetching the cross timestamp i.e. a non-atomic snapshot of the current time from the hardware (WiFi device) clock and system clock (wall-clock) simultaneously. Signed-off-by:

This chip is found in cheap "free driver" USB adapters from Aliexpress. Initially they pretend to be a CD-ROM containing the driver for Windows. "Ejecting" switches the device to wifi mode. Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps. This chip is more unique than other Realtek chips: * The registers at addresses 0x0-0xff, which all the other chips use, can't be used here. New registers at 0x8000-0x80ff must be used instead. And it's not a simple matter of adding 0x8000: 0x2 (REG_SYS_FUNC) became 0x8004, 0x80 (REG_MCU_FW_DL) became 0x8090, etc. * Also there are a few new registers which must be accessed indirectly because their addresses don't fit in 16 bits. No other chips seem to have these. * The vendor driver compiles to 8188gu.ko, but the code calls the chip RTL8710B(U) pretty much everywhere, including messages visible to the user. Another difference compared to the other chips supported by rtl8xxxu is that it has a new PHY status struct, or three of them actually, from which we extract the RSSI, among other things. This is not unique, though, just new. The chips supported by rtw88 also use it. Signed-off-by:

Always run the entire init sequence (rtl8xxxu_init_device()) for RTL8192EU. It's what the vendor driver does too. This fixes a bug where the device is unable to connect after rebooting: wlp3s0f3u2: send auth to ... (try 1/3) wlp3s0f3u2: send auth to ... (try 2/3) wlp3s0f3u2: send auth to ... (try 3/3) wlp3s0f3u2: authentication with ... timed out Rebooting leaves the device powered on (partially? at least the firmware is still running), but not really in a working state.

This can't really be fixed due to the macro layout of tracepoints (you'd need a special tracepoint macro for when this is needed), so just suppress the warnings. Signed-off-by: -

There are a number of issues here: * if trans->reduce_power_loaded is already true, we call iwl_trans_set_reduce_power() with an uninitialized len value * in this case we also clobber a previous load/setting * if iwl_uefi_get_reduced_power() returns an ERR_PTR() we try to kfree() it Move the iwl_trans_set_reduce_power() call into the success case only to fix these issues.

cppcheck reports [drivers/net/wireless/intel/iwlwifi/mvm/rs.c:2686]: (warning) Assignment of function parameter has no effect outside the function. Did you forget dereferencing it? The setting of the 'sta' parameter is not needed. In the if-check that sets it to NULL, mvm_sta is also set to NULL. Then the next statement checks if mvm_sta is NULL and does an early return. So remove setting sta. Signed-off-by:

Refactor MAC_CONTEXT_CMD sending flow: 1. As the new MLD API is introduced, there are some common fields in both the old and new APIs. The MAC_CONTEXT_CMD of the non-MLD API has common fields with the link and mac commands of the new MLD API. Put this common parts in functions so it can be used later by the new MLD API. 2. Use iwl_mvm_mac_ctxt_send_cmd when removing a mac instead of implementing the same functionality once again. 3. Change the debug print when sending the command to be more specific, so it will be easy to distinguish later if the old or new mac command was sent. Signed-off-by:

The HE capability which indicates whether the NIC is ack-enabled or not is the same for all bands. No need to take it from the specific band which is currently in use. Take it from the low band - this simplifies the code and doesn't require a phy_ctxt. Signed-off-by:

In FW restart scenarios, we allocate the queues from the iwl_mvm_realloc_queues_after_restart() function, but that is called before we insert the station ID into our map (mvm->fw_id_to_mac_id). However, in all cases where we're actually allocating a queue for a "real" (not bcast, aux, ...) station we have the sta pointer already, so just pass it along to use it instead of looking it up. This fixes an issue where after restart we only allocated a queue of size 16 (due to the ordering issue described above), and thus never got good throughput again since no aggregates could be formed on transmit.
