- +
- +
- +Supported Platforms
- +===================
- +This driver provides networking support for Freescale DPAA2 SoCs, e.g.
- +LS2080A, LS2088A, LS1088A.
- +
- +
- +Architecture Overview
- +=====================
- +Unlike regular NICs, in the DPAA2 architecture there is no single hardware block
- +representing network interfaces; instead, several separate hardware resources
- +concur to provide the networking functionality:
- + - network interfaces
- + - queues, channels
- + - buffer pools
- + - MAC/PHY
- +
- +All hardware resources are allocated and configured through the Management
- +Complex (MC) portals. MC abstracts most of these resources as DPAA2 objects
- +and exposes ABIs through which they can be configured and controlled. A few
- +hardware resources, like queues, do not have a corresponding MC object and
- +are treated as internal resources of other objects.
- +
- +For a more detailed description of the DPAA2 architecture and its object
- +abstractions see:
- + drivers/staging/fsl-mc/README.txt
- +
- +Each Linux net device is built on top of a Datapath Network Interface (DPNI)
- +object and uses Buffer Pools (DPBPs), I/O Portals (DPIOs) and Concentrators
- +(DPCONs).
- +

- +
- +The DPNIs are network interfaces without a direct one-on-one mapping to PHYs.
- +DPBPs represent hardware buffer pools. Packet I/O is performed in the context
- +of DPCON objects, using DPIO portals for managing and communicating with the
- +hardware resources.

- + ---------------------- | -------------
- + =======================
- + Channel
- +
- +Datapath I/O (DPIO) portals provide enqueue and dequeue services, data
- +availability notifications and buffer pool management. DPIOs are shared between
- +all DPAA2 objects (and implicitly all DPAA2 kernel drivers) that work with data
- +frames, but must be affine to the CPUs for the purpose of traffic distribution.
- +
- +Frames are transmitted and received through hardware frame queues, which can be
- +grouped in channels for the purpose of hardware scheduling. The Ethernet driver
- +enqueues TX frames on egress queues and after transmission is complete a TX
- +confirmation frame is sent back to the CPU.
- +
- +When frames are available on ingress queues, a data availability notification
- +is sent to the CPU; notifications are raised per channel, so even if multiple
- +queues in the same channel have available frames, only one notification is sent.
- +After a channel fires a notification, is must be explicitly rearmed.
- +
- +Each network interface can have multiple Rx, Tx and confirmation queues affined
- +to CPUs, and one channel (DPCON) for each CPU that services at least one queue.
- +DPCONs are used to distribute ingress traffic to different CPUs via the cores'
- +affine DPIOs.
- +
- +The role of hardware buffer pools is storage of ingress frame data. Each network
- +interface has a privately owned buffer pool which it seeds with kernel allocated
- +buffers.
- +
- +
- +DPNIs are decoupled from PHYs; a DPNI can be connected to a PHY through a DPMAC
- +object or to another DPNI through an internal link, but the connection is
- +managed by MC and completely transparent to the Ethernet driver.

- +
- +Creating a Network Interface
- +============================
- +A net device is created for each DPNI object probed on the MC bus. Each DPNI has
- +a number of properties which determine the network interface configuration
- +options and associated hardware resources.
- +
- +DPNI objects (and the other DPAA2 objects needed for a network interface) can be
- +added to a container on the MC bus in one of two ways: statically, through a
- +Datapath Layout Binary file (DPL) that is parsed by MC at boot time; or created
- +dynamically at runtime, via the DPAA2 objects APIs.
- +
- +
- +Features & Offloads
- +===================
- +Hardware checksum offloading is supported for TCP and UDP over IPv4/6 frames.
- +The checksum offloads can be independently configured on RX and TX through
- +ethtool.
- +
- +Hardware offload of unicast and multicast MAC filtering is supported on the
- +ingress path and permanently enabled.
- +
- +Scatter-gather frames are supported on both RX and TX paths. On TX, SG support
- +is configurable via ethtool; on RX it is always enabled.
- +
- +The DPAA2 hardware can process jumbo Ethernet frames of up to 10K bytes.
- +
- +The Ethernet driver defines a static flow hashing scheme that distributes
- +traffic based on a 5-tuple key: src IP, dst IP, IP proto, L4 src port,
- +L4 dst port. No user configuration is supported for now.
- +
- +Hardware specific statistics for the network interface as well as some
- +non-standard driver stats can be consulted through ethtool -S option.
