2019-09-06net: openvswitch: Set OvS recirc_id from tc chain indexPaul Blakey8-5/+95
Offloaded OvS datapath rules are translated one to one to tc rules, for example the following simplified OvS rule: recirc_id(0),in_port(dev1),eth_type(0x0800),ct_state(-trk) actions:ct(),recirc(2) Will be translated to the following tc rule: $ tc filter add dev dev1 ingress \ prio 1 chain 0 proto ip \ flower tcp ct_state -trk \ action ct pipe \ action goto chain 2 Received packets will first travel though tc, and if they aren't stolen by it, like in the above rule, they will continue to OvS datapath. Since we already did some actions (action ct in this case) which might modify the packets, and updated action stats, we would like to continue the proccessing with the correct recirc_id in OvS (here recirc_id(2)) where we left off. To support this, introduce a new skb extension for tc, which will be used for translating tc chain to ovs recirc_id to handle these miss cases. Last tc chain index will be set by tc goto chain action and read by OvS datapath.

2019-09-06iwlwifi: dbg: remove iwl_fw_cancel_dumps functionShahar S Matityahu3-12/+4
Use cancel_delayed_work_sync on the dump workers only in case of unloading the op mode. In any other case use iwl_fw_flush_dumps or iwl_fw_dbg_stop_sync (depends if the op mode mutex is held or not). This way, the driver will wait until debug data is collected in all cases but op mode unloading. Signed-off-by: Shahar S Matityahu <[email protected]> Signed-off-by: Luca Coelho <[email protected]>

2019-09-06iwlwifi: fw api: add DRAM buffer allocation commandShahar S Matityahu3-0/+34
Add support code to be able to use the DRAM buffer allocation command, which allows us to send information about a buffer to the firmware to use it with the DBGC hardware. Signed-off-by: Shahar S Matityahu <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: dbg_ini: remove apply point, switch to time point APIShahar S Matityahu10-568/+101
Remove the "apply points" mechanism as preparation for the changed debug API where this is now a "time point" instead. Use a new API across the code at the trigger points ("time points"), but don't yet implement it since that requires some more preparation.

2019-09-06iwlwifi: mvm: don't log un-decrypted framesEmmanuel Grumbach1-2/+10
Sometimes the firmware won't be able to decrypt frames because the keys were not installed yet or other scenarios. The firmware will soon stop dropping multicast frames when MAC_FILTER_ACCEPT_GRP is not set. The firmware will simply always pass multicast frame in. In order to avoid logging any such frame coming in when we don't have the keys, drop the print. Signed-off-by: Emmanuel Grumbach <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: mvm: add support for single antenna diversityHaim Dreyfuss3-0/+7
There are products which have a single chain with 2 antennas. In these products, we need to inform the FW that the device has the single antenna diversity(SAD) feature. In the future, we will read the active antenna from a BIOS configuration. Currently, we use a default configuration which means that the FW decides which antenna to use.

2019-09-06iwlwifi: mvm: handle BAR_FRAME_RELEASE (0xc2) notificationJohannes Berg5-0/+83
In prior hardware generations (e.g. 9000 series), we received the BAR frame with fake NSSN information to handle releasing frames from the reorder buffer for the default queue, the other queues were getting the FRAME_RELEASE notification in this case. With multi-TID block-ack, the firmware no longer sends us the BAR frame because the fake RX is quite big (just the metadata is around 48 bytes or so). Instead, it now sends us one (or multiple) special release notifications (0xc2). The hardware consumes these as well, but only generates the FRAME_RELEASE (0xc3) for queues other than the default queue. We thus need to handle them in the same way we handle the normal FRAME_RELEASE. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: mvm: drop BA sessions on too many old-SN framesJohannes Berg3-0/+63
Certain APs (I think a certain Broadcom model) interact badly with our full state BA bitmap handling, and if triggered badly with many powersave transitions they keep sending frames from before the window, which our hardware then doesn't appear to ACK (to them) since it has moved on and is sending ACKs for higher SNs now. Try to detect this situation and if this keeps happening, disable the aggregation session. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: add sta_id to WOWLAN_CONFIG_CMDHaim Dreyfuss2-2/+8
WoWlan feature within the FW uses the station id for various of reasons. Thus we need to add this information to the command. Signed-off-by: Haim Dreyfuss <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: add support for suspend-resume flow for new device generationHaim Dreyfuss6-29/+102
The new device generation has a slightly different suspend resume flow Currently, the way the driver instruct the device to move to D3 is by sending D3_CONFIG_CMD. Instead of using the host command the indication is by writing to the doorbell interrupt. The FW will respond with interrupt to indicate transition completion.

2019-09-06iwlwifi: always access the trans configuration via transLuca Coelho21-55/+59
Stop accessing the trans configuration via the iwl_cfg structure and always access it via the iwl_trans structure. This completes the requirements to disassociate the trans-specific configuration from the rest of the configuration. Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: pass the iwl_trans instead of cfg to some functionsShaul Triebitz1-5/+8
A few functions were receiving the iwl_cfg struct directly, but we will also need other parts of the trans, so pass the trans (which includes the cfg) to them.

2019-09-06iwlwifi: add a pointer to the trans_cfg directly in transLuca Coelho29-206/+199
Add a pointer to the iwl_trans structure and point it to the trans part of the cfg. This is the first step in disassociating the trans configuration from the rest of the configuration. Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: pass the iwl_config_trans_params when neededLuca Coelho3-12/+13
Instead of accessing the iwl_config_trans_params from the cfg that is stored in the trans struct, pass this structure directly to functions that need it during trans_alloc. This will be useful to isolate the elements needed during allocation and pass them separately before the actual cfg struct is known. Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: pcie: set iwl_trans->cfg later in the probe functionLuca Coelho4-27/+37
Instead of setting the cfg to iwl_trans already during allocation, set it only later when we have had the time to decide which cfg to use. This is part of the effort to be able to decide the cfg based on HW revision and RF ID after iwl_trans_alloc() has been called. For now, since we still have a bunch of code checking the HW revision and the RF ID, we set iwl_trans->cfg early, even before we decided the real cfg to use. We only use the trans configuration at this point, so this is fine for now. In the future, the trans configuration will be completely independent from the rest of the config structure, so we'll be able to avoid this. Additionally, we can't access the PRPH registers in iwl_trans_alloc() anymore, so move the HW REV C-step check for family 8000 code later to the probe function as well. This step is probably not necessary, but if that's the case it should be removed separately later on. Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: pcie: move some cfg mangling from trans_pcie_alloc to probeLuca Coelho2-99/+76
There were a couple of special handling to find the correct cfg inside iwl_trans_pcie_alloc(). Move them to iwl_pci_probe() so they're together with the rest of the decisions. Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: pcie: use the cfg we passed to iwl_trans_pcie_alloc()Luca Coelho1-3/+3
Instead of using iwl_trans->cfg in iwl_trans_pcie_alloc(), use the local argument that we received. This will allow us to not to set the cfg during iwl_trans_alloc() so it can be decided later. Signed-off-by: Luca Coelho <[email protected]>
2019-09-06iwlwifi: separate elements from cfg that are needed by trans_allocLuca Coelho47-365/+407
In order to be able to select the cfg depending on the HW revision or on the RF ID, we need to set up the trans before selecting the cfg. To do so, move the elements from cfg that are needed by iwl_trans_alloc() to a separate struct at the top of the cfg, so it can be used by other cfg types as well, before selecting the rest of the configuration.

2019-09-06iwlwifi: support per-platform antenna gainGil Adam7-0/+159
TX power limits as defined in the OTP assume the worst case scenario in terms of the platform's atenna gain, but most platforms are below that value so they can use more TX power without passing the regulatory limit. If the platform indicates in the BIOS that it indeed has lower gain, and the geographic location allows it, higher TX power can be used. The driver reads the PPAG (Per-Platform Antenna Gain) data from BIOS (if it exists), validates it and sends the appropriate command to the FW. This flow happens once at FW init, in case of suspend/resume there is no need to read again from BIOS as we save those values during init, so just send the PPAG command again to FW.
