Available on dual port cards only, this feature keeps track, using netdev LAG events, of the bonding and link status of each port's PF netdev. When both of the card's PF netdevs are enslaved to the same bond/team master, and only them, LAG state is active. During LAG, only one IB device is present for both ports. In addition to the above, this commit includes FW commands used for managing the LAG, new facilities for adding and removing a single device by interface, and port remap functionality according to bond events. Please note that this feature is currently used only for mimicking Ethernet bonding for RoCE - netdevs functionality is not altered, and their bonding continues to be managed solely by bond/team driver.

Add support for query the minimum inline mode from the Firmware. It is required for correct TX steering according to L3/L4 packet headers. Each send queue (SQ) has inline mode that defines the minimal required headers that needs to be copied into the SQ WQE. The driver asks the Firmware for the wqe_inline_mode device capability value. In case the device capability defined as "vport context" the driver must check the reported min inline mode from the vport context before creating its SQs.

Start all tx queues (including inactive ones) when opening the netdev. Stop all tx queues (including inactive ones) when closing the netdev. This is a workaround for the tx timeout watchdog false alarm issue in which the netdev watchdog is polling all the tx queues which may include inactive queues and thus once lowering the real tx queues number (ethtool -L) it will generate tx timeout watchdog false alarms.

Implement the relevant profile functions to create mlx5e driver instance serving as VF representor. When SRIOV offloads mode is enabled, each VF will have a representor netdevice instance on the host. To do that, we also export set of shared service functions from en_main.c, such that they can be used by both NIC and repsresentors netdevs. The newly created representor netdevice has a basic set of net_device_ops which are the same ndo functions as the NIC netdevice and an ndo of it's own for phys port name. The profiling infrastructure allow sharing code between the NIC and the vport representor even though the representor has only a subset of the NIC functionality. The VF reps and the PF which is used in that mode to represent the uplink, expose switchdev ops. Currently the only op supposed is attr get for the port parent ID which here serves to identify net-devices belonging to the same HW E-Switch. Other than that, no offloading is implemented and hence switching functionality is achieved if one sets SW switching rules, e.g using tc, bridge or ovs. Port phys name (ndo_get_phys_port_name) is implemented to allow exporting to user-space the VF vport number and along with the switchdev port parent id (phys_switch_id) enable a udev base consistent naming scheme: SUBSYSTEM=="net", ACTION=="add", ATTR{phys_switch_id}=="<phys_switch_id>", \ ATTR{phys_port_name}!="", NAME="$PF_NIC$attr{phys_port_name}" where phys_switch_id is exposed by the PF (and VF reps) and $PF_NIC is the name of the PF netdevice.

To allow support in representor netdevices where we create more than one netdevice per NIC, add profiles to the mlx5e driver. The profiling allows for creation of mlx5e instances with different characteristics. Each profile implements its own behavior using set of function pointers defined in struct mlx5e_profile. This is done to allow for avoiding complex per profix branching in the code. Currently only the profile for the conventional NIC is implemented, which is of use when a netdev is created upon pci probe. This patch doesn't add any new functionality.

In the current driver implementation two types of receive queue tables (RQTs) are in use - direct and indirect. Change the driver to mark each new created RQT (direct or indirect) as "enabled". This behaviour is needed for introducing new mlx5e instances which serve to represent SRIOV VFs. The VF representors will have only one type of RQTs (direct). An "enabled" flag is added to each RQT to allow better handling and code sharing between the representors and the nic netdevices. This patch doesn't add any new functionality.

The current refresh tirs self loopback mechanism, refreshes all the tirs belonging to the same mlx5e instance to prevent self loopback by packets sent over any ring of that instance. This mechanism relies on all the tirs/tises of an instance to be created with the same transport domain number (tdn). Change the driver to refresh all the tirs created under the same tdn regardless of which mlx5e netdev instance they belong to. This behaviour is needed for introducing new mlx5e instances which serve to represent SRIOV VFs. The representors and the PF share vport used for E-Switch management, and we want to avoid NIC level HW loopback between them, e.g when sending broadcast packets. To achieve that, both the representors and the PF NIC will share the tdn. This patch doesn't add any new functionality.

The default fallback function used by mlx5e select queue can return any TX queues in range [0..dev->num_real_tx_queues). The current implementation assumes that the fallback function returns a number in the range [0.. number of channels). Actually dev->num_real_tx_queues = (number of channels) * dev->num_tc; which is more than the expected range if num_tc is configured and could lead to crashes. To fix this we test if num_tc is not configured we can safely return the fallback suggestion, if not we will reciprocal_scale the fallback result and normalize it to the desired range.

In this mode the moderation timer will restart upon new completion (CQE) generation rather than upon interrupt generation. The outcome is that for bursty traffic the period timer will never expire and thus only the moderation frames counter will dictate interrupt generation, thus the interrupt rate will be relative to the incoming packets size. If the burst seizes for "moderation period" time then an interrupt will be issued immediately. CQE based moderation is off by default and can be controlled via ethtool set_priv_flags. Performance tested on ConnectX4-Lx 50G. Less packet loss in netperf UDP and TCP tests, with no bw degradation, for both single and multi streams, with message sizes of 64, 1024, 1472 and 32768 byte.
