Similar to rtl_fw_data_ok() we can simplify the code by moving incrementing the index to the for loop initialization. Signed-off-by:

Replace the firmware opcode defines with a proper enum. The BUG() in rtl_fw_write_firmware() can be removed because the call to rtl_fw_data_ok() ensures all opcodes are valid. Signed-off-by:

Huazhong Tan says: ==================== code optimizations & bugfixes for HNS3 driver This patch-set includes code optimizations and bugfixes for the HNS3 ethernet controller driver. [patch 1/10] removes the redundant core reset type [patch 2/10 - 3/10] fixes two VLAN related issues [patch 4/10] fixes a TM issue [patch 5/10 - 10/10] includes some patches related to RAS & MSI-X error Change log: V1->V2: removes two patches which needs to change HNS's infiniband driver as well, they will be upstreamed later with the infiniband's one. ==================== Signed-off-by: -

All RAS and MSI-X should be enabled just in the final stage of HNS3 initialization. It means that they should be enabled in hclge_init_xxx_client_instance instead of hclge_ae_dev(). Especially MSI-X, if it is enabled before opening vector0 IRQ, there are some chances that a MSI-X error will cause failure on initialization of NIC client instane. So this patch delays enabling of HW errors. Otherwise, we also separate enabling of ROCE RAS from NIC, because it's not reasonable to enable ROCE RAS if we even don't have a ROCE driver.

There are four commands being used to query and clear RAS and MSI-X interrupts status. They should be contained in array of special opcodes because these commands have several descriptors, and we need to judge return value in the first descriptor rather than the last one as other opcodes. In addition, we shouldn't set the NEXT_FLAG of first descriptor. This patch fixes above issues. Signed-off-by:

LINK_UP and LINK_DOWN are two bits of MAC tunnel interrupts, but previous HNS3 driver didn't handle them. If they were enabled, value of these two bits will change during link down and link up, which will cause HNS3 driver keep receiving IRQ but can't handle them. This patch adds handling of these two bits of interrupts, we will record and clear them as what we do to other MAC tunnel interrupts. Signed-off-by:

The hclge/hclgevf and hns3 module can be unloaded independently, when hclge/hclgevf unloaded firstly, the ops of ae_dev should be set to NULL, otherwise it will cause an use-after-free problem. Fixes: 38caee9d ("net: hns3: Add support of the HNAE3 framework") Signed-off-by:

If we add a VF without loading hclgevf.ko and then there is a RAS error occurs, PCIe AER will call error_detected and slot_reset of all functions, and will get a NULL pointer when we check ad_dev->ops->handle_hw_ras_error. This will cause a call trace and failures on handling of follow-up RAS errors. This patch check ae_dev and ad_dev->ops at first to solve above issues. Signed-off-by:

In orginal codes, the driver only restore VLAN filter entries for PF after reset, the VLAN entries of VF will lose in this case. This patch fixes it by recording VLAN IDs for each function when add VLAN, and restore the VLAN IDs after reset.

VF VLAN table can only support no more than 256 VLANs. When user adds too many VLANs, the VF VLAN table will be full, and firmware will close the VF VLAN table for the function. When VF VLAN table is full, and user keeps adding new VLANs, it's unnecessary to configure the VF VLAN table, because it will always fail, and print warning message. The worst case is adding 4K VLANs, and doing reset, it will take much time to restore these VLANs, which may cause VF reset fail by timeout.

Sean Wang says: ==================== Add MT7629 ethernet support MT7629 inlcudes two sets of SGMIIs used for external switch or PHY, and embedded switch (ESW) via GDM1, GePHY via GMAC2, so add several patches in the series to make the code base common with the old SoCs. The patch 1, 3 and 6, adds extension for SGMII to have the hardware configured for 1G, 2.5G and AN to fit the capability of the target PHY. In patch 6 could be an example showing how to use these configurations for underlying PHY speed to match up the link speed of the target PHY. The patch 4 is used for automatically configured the hardware path from GMACx to the target PHY by the description in deviceetree topology to determine the proper value for the corresponding MUX. The patch 2 and 5 is for the update for MT7629 including dt-binding document and its driver. ==================== Signed-off-by: -

Saeed Mahameed says: ==================== mlx5-updates-2019-05-31 This series provides some updates to mlx5 core and netdevice driver. 1) use __netdev_tx_sent_queue() to improve performance under GSO workload 2) Allow matching only enc_key_id/enc_dst_port for decapsulation action 3) Geneve support: This patchset adds support for GENEVE tunnel encap/decap flows offload: encapsulating layer 2 Ethernet frames within layer 4 UDP datagrams. The driver supports 6081 destination UDP port number, which is the default IANA-assigned port. Encap: ConnectX-5 inserts the header (w/ or w/o Geneve TLV options) that is provided by the mlx5 driver to the outgoing packet. Decap: Geneve header is matched and the packet is decapsulated. Notes about decap flows with Geneve TLV Options: - Support offloading of 32-bit options data only - At any given time, only one combination of class/type parameters can be offloaded, but the same class/type combination can have many different flows offloaded with different 32-bit option data - Options with value of 0 can't be offloaded Managing Geneve TLV options: Matching (on receive) is done by ConnectX-5 flex parser. Geneve TLV options are managed using General Object of type “Geneve TLV Options”. When the first flow with a certain class/type values is requested to be offloaded, the driver creates a FW object with FW command (Geneve TLV Options general object) and starts counting the number of flows using this object. During this time, any request with a different class/type values will fail to be offloaded. Once the refcount reaches 0, the driver destroys the TLV options general object, and can now offload a flow with any class/type parameters. Geneve TLV Options object is added to core device. It is currently used to manage Geneve TLV options general object allocation in FW and its reference counting only. In the future it will also be used for managing geneve ports by registering callbacks for ndo_udp_tunnel_add/del. TC tunnel code refactoring: As a preparation for Geneve code, the TC tunnel code in mlx5 was rearranged in a modular way, so that it would be easier to add future tunnels: - Defined tc tunnel object with the fields and callbacks that any tunnel must implement. - Define tc UDP tunnel object for UDP tunnels, such as VXLAN - Move each tunnel code (GRE, VXLAN) to its own separate file - Rewrite tc tunnel implementation in a general way – using only the objects and their callbacks. 4) Termination tables: Actions in tables set with the termination flag are guaranteed to terminate the action list. Thus, potential looping functionality (e.g. haripin) can safely be executed without potential loops. ==================== Signed-off-by: -

Up until now the driver always used a single setting for the sizes of the different parts of the llq entry - 128 for entry size, 2 for descriptors before header and 96 for maximum header size. The current code makes sure that the parts of the llq entry are compatible with each other and with the initial llq entry size given by the device. This commit changes this code to support any llq entry size Signed-off-by:

struct ena_ring holds a union of free_rx_ids and free_tx_ids. Both of the above fields mean the exact same thing and are used exactly the same way. Furthermore, these fields are always used with a prefix of the type of ring. So for tx it will be tx_ring->free_tx_ids, and for rx it will be rx_ring->free_rx_ids, which shows how redundant the "_tx" and "_rx" parts are. Furthermore still, this may lead to confusing code like where tx_ring->free_rx_ids which works correctly but looks like a mess. This commit removes the aforementioned redundancy by replacing the free_rx/tx_ids union with a single free_ids field. It also changes a single goto label name from err_free_tx_ids: to err_tx_free_ids: for consistency with the above new notation. Signed-off-by:
