2017-08-31ath10k: activate user space firmware loading againHauke Mehrtens
In commit 9f5bcfe93315 ("ath10k: silence firmware file probing warnings") the firmware loading was changed from request_firmware() to request_firmware_direct() to silence some warnings in case it fails. request_firmware_direct() directly searches in the file system only and does not send a hotplug event to user space in case it could not find the firmware directly. In LEDE we use a user space script to extract the calibration data from the flash memory which gets triggered by the hotplug event. This way the firmware gets extracted from some vendor specific partition when the driver requests this firmware. This mechanism does not work any more after this change.

2017-08-31ath10k: fix napi_poll budget overflowRyan Hsu
In napi_poll, the budget number is used to control the amount of packets we should handle per poll to balance the resource in the system. In the list of the amsdu packets reception, we check if there is budget count left and handle the complete list of the packets, that it will have chances the very last list will over the budget leftover. So adding one more parameter - budget_left, this would help while traversing the list to avoid handling more than the budget given.

The first patch from Gal and Ariel provides the mlx5 driver support for ConnectX capability to perform IP version identification and matching in order to distinguish between IPv4 and IPv6 without the need to specify the encapsulation type, thus perform RSS in MPLS automatically without specifying MPLS ethertyoe. This patch will also serve for inner GRE IPv4/6 classification for inner GRE RSS. 2nd patch from Gal, Adds the TX offloads support for GRE tunneled packets, by reporting the needed netdev features. 3rd patch from Gal, Adds GRE inner RSS support by creating the needed device resources (Steering Tables/rules and traffic classifiers) to Match GRE traffic and perform RSS hashing on the inner headers.

Fix crash in linux PF driver when BARs have been cleared/de-programmed; fail early init (prior to mapping BARs) if the BAR0 or BAR1 registers are zero. This situation can arise when the PF is added to a VM (PCI pass-through), then a PF FLR is issued (in the VM). After this occurs, the BAR registers will be zero.

2017-08-31net/mlx5e: Support RSS for GRE tunneled packetsGal Pressman
Introduce a new flow table and indirect TIRs which are used to hash the inner packet headers of GRE tunneled packets. When a GRE tunneled packet is received, the TTC flow table will match the new IPv4/6->GRE rules which will forward it to the inner TTC table. The inner TTC is similar to its counterpart outer TTC table, but matching the inner packet headers instead of the outer ones (and does not include the new IPv4/6->GRE rules). The new rules will not add steering hops since they are added to an already existing flow group which will be matched regardless of this patch. Non GRE traffic will not be affected. The inner flow table will forward the packet to inner indirect TIRs which hash the inner packet and thus result in RSS for the tunneled packets.

2017-08-31net/mlx5e: Use IP version matching to classify IP trafficGal Pressman
This change adds the ability for flow steering to classify IPv4/6 packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP packets and hit IPv4/6 classification steering rules. Since IP packets with MPLS tag header have MPLS ethertype, they missed the IPv4/6 ethertype rule and ended up hitting the default filter forwarding all the packets to the same single RQ (No RSS). Since our device is able to look past the MPLS tag and identify the next protocol we introduce this solution which replaces ethertype matching by the device's capability to perform IP version identification and matching in order to distinguish between IPv4 and IPv6. Therefore, when driver is performing flow steering configuration on the device it will use IP version matching in IP classified rules instead of ethertype matching which will cause relevant MPLS tagged packets to hit this rule as well. If the device doesn't support IP version matching the driver will fall back to use legacy ethertype matching in the steering as before.

Support for ISSI version 0 was recently broken as the arm_srq_cmd command, which is used only for ISSI version 0, was given the opcode for ISSI version 1 instead of ISSI version 0. Change arm_srq_cmd to use the correct command opcode for ISSI version 0.

2017-08-30net/mlx5e: Fix DCB_CAP_ATTR_DCBX capability for DCBNL getcap.Huy Nguyen
Current code doesn't report DCB_CAP_DCBX_HOST capability when query through getcap. User space lldptool expects capability to have HOST mode set when it wants to configure DCBX CEE mode. In absence of HOST mode capability, lldptool fails to switch to CEE mode. This fix returns DCB_CAP_DCBX_HOST capability when port's DCBX controlled mode is under software control.

2017-08-30net: ti: cpsw-common: dont print error if ti_cm_get_macid() failsSekhar Nori
It is quite common for ti_cm_get_macid() to fail on some of the platforms it is invoked on. They include any platform where mac address is not part of SoC register space. On these platforms, mac address is read and populated in device-tree by bootloader. An example is TI DA850. Downgrade the severity of message to "information", so it does not spam logs when 'quiet' boot is desired. Signed-off-by: Sekhar Nori <nsekhar@ti.com> Signed-off-by: David S.

2017-08-30iwlwifi: mvm: Avoid deferring non bufferable framesDavid Spinadel
Use bcast station for all non bufferable frames on AP and AD-HOC. The host is no longer aware of STAs PS status because of buffer station offload, so we can't rely on mac80211 to toggle on IEEE80211_TX_CTL_NO_PS_BUFFER bit. A possible issue with buffering such frames, beside the obvious spec violation, is when a station disconnects while in PS but the AP isn't aware of that. In such scenarios the AP won't be able to send probe responses or auth frames so the STA won't be able to reconnect and the AP will have a queue hang.
