2020-03-26net: atlantic: MACSec offload skeletonDmitry Bogdanov
This patch adds basic functionality for MACSec offloading for Atlantic NICs. MACSec offloading functionality is enabled if network card has appropriate FW that has MACSec offloading enabled in config. Actual functionality (ingress, egress, etc) will be added in follow-up patches.

2020-03-26net: macsec: report real_dev features when HW offloading is enabledMark Starovoytov
This patch makes real_dev_feature propagation by MACSec offloaded device. Issue description: real_dev features are disabled upon macsec creation. Root cause: Features limitation (specific to SW MACSec limitation) is being applied to HW offloaded case as well. This causes 'set_features' request on the real_dev with reduced feature set due to chain propagation. Proposed solution: Report real_dev features when HW offloading is enabled. NB! MACSec offloaded device does not propagate VLAN offload features at the moment. This can potentially be added later on as a separate patch. Note: this patch requires HW offloading to be enabled by default in order to function properly.

2020-03-26net: ethernet: ti: introduce am65x/j721e gigabit eth subsystem driverGrygorii Strashko
The TI AM65x/J721E SoCs Gigabit Ethernet Switch subsystem (CPSW2G NUSS) has two ports - One Ethernet port (port 1) with selectable RGMII and RMII interfaces and an internal Communications Port Programming Interface (CPPI) port (Host port 0) and with ALE in between. It also contains - Management Data Input/Output (MDIO) interface for physical layer device (PHY) management; - Updated Address Lookup Engine (ALE) module; - (TBD) New version of Common platform time sync (CPTS) module. On the TI am65x/J721E SoCs CPSW NUSS Ethernet subsystem into device MCU domain named MCU_CPSW0. Host Port 0 CPPI Packet Streaming Interface interface supports 8 TX channels and one RX channels operating by TI am654 NAVSS Unified DMA Peripheral Root Complex (UDMA-P) controller. Introduced driver provides standard Linux net_device to user space and supports: - ifconfig up/down - MAC address configuration - ethtool operation: --driver --change --register-dump --negotiate phy --statistics --set-eee phy --show-ring --show-channels --set-channels - net_device ioctl mii-control - promisc mode - rx checksum offload for non-fragmented IPv4/IPv6 TCP/UDP packets. The CPSW NUSS can verify IPv4/IPv6 TCP/UDP packets checksum and fills csum information for each packet in psdata[2] word: - BIT(16) CHECKSUM_ERROR - indicates csum error - BIT(17) FRAGMENT - indicates fragmented packet - BIT(18) TCP_UDP_N - Indicates TCP packet was detected - BIT(19) IPV6_VALID, BIT(20) IPV4_VALID - indicates IPv6/IPv4 packet - BIT(15, 0) CHECKSUM_ADD - This is the value that was summed during the checksum computation. This value is FFFFh for non fragmented IPV4/6 UDP/TCP packets with no checksum error. RX csum offload can be disabled: ethtool -K <dev> rx-checksum on|off - tx checksum offload support for IPv4/IPv6 TCP/UDP packets (J721E only). TX csum HW offload can be enabled/disabled: ethtool -K <dev> tx-checksum-ip-generic on|off - multiq and switch between round robin/prio modes for cppi tx queues by using Netdev private flag "p0-rx-ptype-rrobin" to switch between Round Robin and Fixed priority modes: # ethtool --show-priv-flags eth0 Private flags for eth0: p0-rx-ptype-rrobin: on # ethtool --set-priv-flags eth0 p0-rx-ptype-rrobin off Number of TX DMA channels can be changed using "ethtool -L eth0 tx <N>". - GRO support: the napi_gro_receive() and napi_complete_done() are used.

2020-03-26net: ethernet: ti: ale: add support for mac-only modeGrygorii Strashko
The new CPSW ALE version, available on TI K3 AM654/J721E SoCs family, allows to switch any external port to MAC only mode. When MAC only mode enabled this port be treated like a MAC port for the host. All traffic received is only sent to the host. The host must direct traffic to this port as the lookup engine will not send traffic to the ports with the p0_maconly bit set and the p0_no_learn also set. If p0_maconly bit is set and the p0_no_learn is not set, the host can send non-directed packets that can be sent to the destination of a MacOnly port. It is also possible that The host can broadcast to all ports including MacOnly ports in this mode. This patch add ALE supprt for MAC only mode.

allmulti disabled On AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS the unregistered multicast packets are still can be received with promisc and allmulti disabled. This happens, because ALE VLAN entries on these SoCs do not contain port masks for reg/unreg mcast packets, but instead store indexes of ALE_VLAN_MASK_MUXx_REG registers which intended for store port masks for reg/unreg mcast packets. ALE VLAN entry:UNREG_MCAST_FLOOD_INDEX -> ALE_VLAN_MASK_MUXx ALE VLAN entry:REG_MCAST_FLOOD_INDEX -> ALE_VLAN_MASK_MUXy The commit b361da837392 ("net: netcp: ale: add proper ale entry mask bits for netcp switch ALE") update ALE code to support such ALE entries, it is always used ALE_VLAN_MASK_MUX0_REG index in ALE VLAN entry for unreg mcast packets mask configuration, which is read-only, at least for AM65xx MCU CPSW2G NUSS and 66AK2E/L NUSS. As result unreg mcast packets are allowed always. Hence, update ALE code to use ALE_VLAN_MASK_MUX1_REG index for ALE VLAN entries to configure unreg mcast port mask.

2020-03-26net: phy: probe PHY drivers synchronouslyHeiner Kallweit
If we have scenarios like mdiobus_register() -> loads PHY driver module(s) -> registers PHY driver(s) -> may schedule async probe phydev = mdiobus_get_phy() <phydev action involving PHY driver> or phydev = phy_device_create() -> loads PHY driver module -> registers PHY driver -> may schedule async probe <phydev action involving PHY driver> then we expect the PHY driver to be bound to the phydev when triggering the action. This may not be the case in case of asynchronous probing. Therefore ensure that PHY drivers are probed synchronously. Default still is sync probing, except async probing is explicitly requested. I saw some comments that the intention is to promote async probing for more parallelism in boot process and want to be prepared for the case that the default is changed to async probing.

2020-03-26devlink: track snapshot id usage count using an xarrayJacob Keller
Each snapshot created for a devlink region must have an id. These ids are supposed to be unique per "event" that caused the snapshot to be created. Drivers call devlink_region_snapshot_id_get to obtain a new id to use for a new event trigger. The id values are tracked per devlink, so that the same id number can be used if a triggering event creates multiple snapshots on different regions. There is no mechanism for snapshot ids to ever be reused. Introduce an xarray to store the count of how many snapshots are using a given id, replacing the snapshot_id field previously used for picking the next id. The devlink_region_snapshot_id_get() function will use xa_alloc to insert an initial value of 1 value at an available slot between 0 and U32_MAX. The new __devlink_snapshot_id_increment() and __devlink_snapshot_id_decrement() functions will be used to track how many snapshots currently use an id. Drivers must now call devlink_snapshot_id_put() in order to release their reference of the snapshot id after adding region snapshots. By tracking the total number of snapshots using a given id, it is possible for the decrement() function to erase the id from the xarray when it is not in use. With this method, a snapshot id can become reused again once all snapshots that referred to it have been deleted via DEVLINK_CMD_REGION_DEL, and the driver has finished adding snapshots. This work also paves the way to introduce a mechanism for userspace to request a snapshot.

2020-03-26devlink: report error once U32_MAX snapshot ids have been usedJacob Keller
The devlink_snapshot_id_get() function returns a snapshot id. The snapshot id is a u32, so there is no way to indicate an error code. A future change is going to possibly add additional cases where this function could fail. Refactor the function to return the snapshot id in an argument, so that it can return zero or an error value. This ensures that snapshot ids cannot be confused with error values, and aids in the future refactor of snapshot id allocation management. Because there is no current way to release previously used snapshot ids, add a simple check ensuring that an error is reported in case the snapshot_id would over flow.

Modify the devlink region code in preparation for adding new operations on regions. Create a devlink_region_ops structure, and move the name pointer from within the devlink_region structure into the ops structure (similar to the devlink_health_reporter_ops). This prepares the regions to enable support of additional operations in the future such as requesting snapshots, or accessing the region directly without a snapshot. In order to re-use the constant strings in the mlx4 driver their declaration must be changed to 'const char * const' to ensure the compiler realizes that both the data and the pointer cannot change.
