Implement ndo_setup_tc net device callback for TC HW offload on PF device.
ndo_setup_tc provides support for HW offloading various TC filters. Add support for configuring the following filter with tc-flower: - default L2 filters (src/dst mac addresses, ethertype, VLAN) - variations of L3, L3+L4, L2+L3+L4 filters using advanced filters (including ipv4 and ipv6 addresses).
Allow for adding/removing TC flows when PF device is configured in eswitch switchdev mode. Two types of actions are supported at the moment: FLOW_ACTION_DROP and FLOW_ACTION_REDIRECT.

Michal Swiatkowski says:
The following patch series introduces basic switchdev model support in ice driver. Implement the following blocks of switchdev framework: - VF port representors creation - control plane VSI definition - exception path (a. k. a. "slow-path") - to allow a virtual switch or linux bridge to receive any packet that doesn't match any hw filter - link state management of virtual ports - query virtual port statistics
Hardware offload support in switchdev mode is out of scope of this patchset. Devlink interface is used to toggle between switchdev and legacy (the default) modes of the driver.
--- Note: This series includes the use enum ice_status, however, we have patches in our queue to remove it from the driver [1]. We are working through the patches that precede the removal series.

ice: introduce VF port representor
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.

ice: support basic E-Switch mode control
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

==================== 100GbE Intel Wired LAN Driver Updates 2021-06-11
Extend the ice driver to support basic PTP clock functionality for E810 devices.
This includes some tangential work required to setup the sideband queue and driver shared parameters as well.
This series only supports E810-based devices. This is because other devices based on the E822 MAC use a different and more complex PHY.
The low level device functionality is kept within ice_ptp_hw.c and is designed to be extensible for supporting E822 devices in a future series.
This series also only supports very basic functionality including the ptp_clock device and timestamping. Support for configuring periodic outputs and external input timestamps will be implemented in a future series.
There are a couple of potential "what? why?" bits in this series I want to point out:
1) the PTP hardware functionality is shared between multiple functions. This means that the same clock registers are shared across multiple PFs. In order to avoid contention or clashing between PFs, firmware assigns "ownership" to one PF, while other PFs are merely "associated" with the timer. Because we share the hardware resource, only the clock owner will allocate and register a PTP clock device. Other PFs determine the appropriate PTP clock index to report by using a firmware interface to read a shared parameter that is set by the owning PF.
2) the ice driver uses its own kthread instead of using do_aux_work. This is because the periodic and asynchronous tasks are necessary for all PFs, but only one PF will allocate the clock.
The series is broken up into functional pieces to allow easy review. ====================

Add a new ice_ptp.c file for holding the basic PTP clock interface functions. If the device supports PTP, call the new ice_ptp_init and ice_ptp_release functions where appropriate.
If the function owns the hardware resource associated with the PTP hardware clock, register with the PTP_1588_CLOCK infrastructure to allocate a new clock object that represents the device hardware clock.
Implement basic functionality for reading and setting the clock time, performing clock adjustments, and adjusting the clock frequency.
Future changes will introduce functionality for handling related features including Tx and Rx timestamps.

Merge branch 'irdma' into rdma.git for-next
Shiraz Saleem says:
==================== Add Intel Ethernet Protocol Driver for RDMA (irdma)
The following patch series introduces a unified Intel Ethernet Protocol Driver for RDMA (irdma) for the X722 iWARP device and a new E810 device which supports iWARP and RoCEv2. The irdma module replaces the legacy i40iw module for X722 and extends the ABI already defined for i40iw. It is backward compatible with legacy X722 rdma-core provider (libi40iw).
X722 and E810 are PCI network devices that are RDMA capable. The RDMA block of this parent device is represented via an auxiliary device exported to 'irdma' using the core auxiliary bus infrastructure recently added for 5.11 kernel. The parent PCI netdev drivers 'i40e' and 'ice' register auxiliary RDMA devices with private data/ops encapsulated that bind to auxiliary drivers registered in irdma module.
Currently, default is RoCEv2 for E810. Runtime support for protocol switch to iWARP will be made available via devlink in a future patch. ====================

Merge branch 'iwl-next' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/linux
Tony Nguyen says:
==================== iwl-next Intel Wired LAN Driver Updates 2021-06-01
This pull request is targeting net-next and rdma-next branches. These patches have been reviewed by netdev and rdma mailing lists[1].
This series adds RDMA support to the ice driver for E810 devices and converts the i40e driver to use the auxiliary bus infrastructure for X722 devices. The PCI netdev drivers register auxiliary RDMA devices that will bind to auxiliary drivers registered by the new irdma module.
[1] https://lore.kernel.org/netdev/20210520143809.819-1-shiraz.saleem@intel.com/ --- v3: - ice_aq_add_rdma_qsets(), ice_cfg_vsi_rdma(), ice_[ena|dis]_vsi_rdma_qset(), and ice_cfg_rdma_fltr() no longer return ice_status - Remove null check from ice_aq_add_rdma_qsets()
v2: - Added patch 'i40e: Replace one-element array with flexible-array member'
Changes since linked review (v6): - Removed unnecessary checks in i40e_client_device_register() and i40e_client_device_unregister() - Simplified the i40e_client_device_register() API ====================
