2021-10-08net: enetc: add support for software TSOIoana Ciornei4-24/+311
This patch adds support for driver level TSO in the enetc driver using the TSO API. Beside using the usual tso_build_hdr(), tso_build_data() this specific implementation also has to compute the checksum, both IP and L4, for each resulted segment. This is because the ENETC controller does not support Tx checksum offload which is needed in order to take advantage of TSO. With the workaround for the ENETC MDIO erratum in place the Tx path of the driver is forced to lock/unlock for each skb sent. This is why, even though we are computing the checksum by hand we see the following improvement in TCP termination on the LS1028A SoC, on a single A72 core running at 1.3GHz: before: 1.63 Gbits/sec after: 2.34 Gbits/sec Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Reviewed-by: Claudiu Manoil <claudiu.manoil@nxp.com> Reviewed-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

Trying to bind a MDIO device with a PHYLIB driver results in out-of- bounds accesses as we attempt to access struct phy_device members.

Slow path means allowing packet to go from uplink to representor and from representor to correct VF on Rx site and from VF to representor and to uplink on Tx site. To accomplish this driver, has to set correct Tx descriptor. When packet is sent from representor to VF, destination should be set to VF VSI. When packet is sent from uplink port destination should be uplink to bypass switch infrastructure and send packet outside. On Rx site driver should check source VSI field from Rx descriptor and based on that forward packed to correct netdev. To allow this there is a target netdevs table in control plane VSI struct.

Implement helper functions to start and stop all representors queues. This is used to disable traffic on port representors.

New type of VSI has to be defined for switchdev control plane VSI. Number of allocated Tx and Rx queue has to be equal to amount of VFs, because each port representor should have one Tx and Rx queue. Also to not increase number of used irqs too much, control plane VSI uses only one q_vector and handle all queues in one irq. To allow handling all queues in one irq , new function to clean msix for eswitch was introduced. This function will schedule napi for each representor instead of scheduling it only for one like in normal clean irq function. Only one additional msix has to be requested.

2021-10-07ice: set and release switchdev environmentGrzegorz Nitka6-13/+453
Switchdev environment has to be set up when user create VFs and eswitch mode is switchdev. Release is done when user delete all VFs. Data path in this implementation is based on control plane VSI. This VSI is used to pass traffic from port representors to corresponding VFs and vice versa. Default TX rule has to be added to forward packet to control plane VSI. This will redirect packets from VFs which don't match other rules to control plane VSI. On RX side default rule is added on uplink VSI to receive all traffic that doesn't match other rules. When setting switchdev environment all other rules from VFs should be removed. Packet to VFs will be forwarded by control plane VSI. As VF without any mac rules can't send any packet because of antispoof mechanism, VSI antispoof should be turned off on each VFs. To send packet from representor to correct VSI, destination VSI field in TX descriptor will have to be filled. Allow that by setting destination override bit in control plane VSI security config. Packet from VFs will be received on control plane VSI. Driver should decide to which netdev forward the packet. Decision is made based on src_vsi field from descriptor. There is a target netdev list in control plane VSI struct which choose netdev based on src_vsi number.

2021-10-07ice: introduce VF port representorMichal Swiatkowski6-2/+286
Port representor is used to manage VF from host side. To allow it each created representor registers netdevice with random hw address. Also devlink port is created for all representors. Port representor name is created based on switch id or managed by devlink core if devlink port was registered with success. Open and stop ndo ops are implemented to allow managing the VF link state. Link state is tracked in VF struct. Struct ice_netdev_priv is extended by pointer to representor field. This is needed to get correct representor from netdev struct mostly used in ndo calls. Implement helper functions to check if given netdev is netdev of port representor (ice_is_port_repr_netdev) and to get representor from netdev (ice_netdev_to_repr). As driver mostly will create or destroy port representors on all VFs instead of on single one, write functions to add and remove representor for each VF. Representor struct contains pointer to source VSI, which is VSI configured on VF, backpointer to VF, backpointer to netdev, q_vector pointer and metadata_dst which will be used in data path.

Keeping devlink port inside VSI data structure causes some issues. Since VF VSI is released during reset that means that we have to unregister devlink port and register it again every time reset is triggered. With the new changes in devlink API it might cause deadlock issues. After calling devlink_port_register/devlink_port_unregister devlink API is going to lock rtnl_mutex. It's an issue when VF reset is triggered in netlink operation context (like setting VF MAC address or VLAN), because rtnl_lock is already taken by netlink. Another call of rtnl_lock from devlink API results in dead-lock. By moving devlink port to PF/VF we avoid creating/destroying it during reset. Since this patch, devlink ports are created during ice_probe, destroyed during ice_remove for PF and created during ice_repr_add, destroyed during ice_repr_rem for VF.

2021-10-07ice: support basic E-Switch mode controlMichal Swiatkowski6-0/+116
Write set and get eswitch mode functions used by devlink ops. Use new pf struct member eswitch_mode to track current eswitch mode in driver. Changing eswitch mode is only allowed when there are no VFs created. Create new file for eswitch related code. Add config flag ICE_SWITCHDEV to allow user to choose if switchdev support should be enabled or disabled. Use case examples: - show current eswitch mode ('legacy' is the default one) [root@localhost]# devlink dev eswitch show pci/0000:03:00.1 pci/0000:03:00.1: mode legacy - move to 'switchdev' mode [root@localhost]# devlink dev eswitch set pci/0000:03:00.1 mode switchdev [root@localhost]# devlink dev eswitch show pci/0000:03:00.1 pci/0000:03:00.1: mode switchdev - create 2 VFs [root@localhost]# echo 2 > /sys/class/net/ens4f1/device/sriov_numvfs - unsuccessful attempt to change eswitch mode while VFs are created [root@localhost]# devlink dev eswitch set pci/0000:03:00.1 mode legacy devlink answers: Operation not supported - destroy VFs [root@localhost]# echo 0 > /sys/class/net/ens4f1/device/sriov_numvfs - restore 'legacy' mode [root@localhost]# devlink dev eswitch set pci/0000:03:00.1 mode legacy [root@localhost]# devlink dev eswitch show pci/0000:03:00.1 pci/0000:03:00.1: mode legacy Co-developed-by: Grzegorz Nitka <grzegorz.nitka@intel.com> Signed-off-by: Grzegorz Nitka <grzegorz.nitka@intel.com> Signed-off-by: Michal Swiatkowski <michal.swiatkowski@linux.intel.com> Tested-by: Sandeep Penigalapati <sandeep.penigalapati@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

None of the callers care about the actual value, only if it's NULL or not.

2021-10-07mlxsw: Add ability to control transceiver modules' power modeIdo Schimmel4-3/+254
Implement support for ethtool_ops::.get_module_power_mode and ethtool_ops::set_module_power_mode. The get operation is implemented using the Management Cable IO and Notifications (MCION) register that reports the operational power mode of the module and its presence. In case a module is not present, its operational power mode is not reported to ethtool and user space. If not set before, the power mode policy is reported as "high", which is the default on Mellanox systems. The set operation is implemented using the Port Module Memory Map Properties (PMMP) register. The register instructs the device's firmware to transition a plugged-in module to / out of low power mode by writing to its memory map. When the power mode policy is set to 'auto', a module will not transition to low power mode as long as any ports using it are administratively up. Example: # devlink port split swp11 count 4 # ethtool --set-module swp11s0 power-mode-policy auto $ ethtool --show-module swp11s0 Module parameters for swp11s0: power-mode-policy auto power-mode low # ip link set dev swp11s0 up # ip link set dev swp11s1 up $ ethtool --show-module swp11s0 Module parameters for swp11s0: power-mode-policy auto power-mode high # ip link set dev swp11s1 down $ ethtool --show-module swp11s0 Module parameters for swp11s0: power-mode-policy auto power-mode high # ip link set dev swp11s0 down $ ethtool --show-module swp11s0 Module parameters for swp11s0: power-mode-policy auto power-mode low Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
