This doesn't readily work on FMANv3 devices,such as the T-series powerpc, or the LS1043 ARM. Since Freescale/NXPabandoned the NCSW driver a decade ago, it makes sense to abandon itourselves as well. This new driver uses a combination of the NCSWdriver and the Linux driver (BSD/GPL dual licensed) as a reference, butcontains no actual code from them.The DPAA (Data Path Acceleration Architecture) subsystem consists of thefollowing components:* BMan -- Buffer Manager. Manages buffer pools of different sizes (one size per pool, up to 64 pools)* QMan -- Queue Manager. Manages the interfaces between DPAA-based components and the CPU(s).* FMan -- Frame Manager. Responsible for all ethernet-related processing. Consists itself of the following components: * Ports -- interfaces to the QMan. An ethernet interface consists of 2 ports. Ports use "Next-invoked action" (NIA) descriptors to form a pipeline for processing on receive and transmit. * Parser -- performs protocol header parsing and validation. Both hardware and software parsers are available. * KeyGen -- Key generator, used to start the classification process (for the Policer), generating FQIDs and other keys based on the frame input. * Policer -- performs traffic shaping and classification* MAC -- SoC specific ethernet MAC (dTSEC, TGEC, mEMAC). Currently supports dTSEC and mEMAC, along with their MDIO blocks.Additional components not yet handled:SEC -- Security engine (crypto)RE -- RAID engineRapidIODCE -- Decompression/Compression engine, supports ZLIB, DEFLATE, andGZIP, as well as base64 encoding and decoding.BMan and QMan are accessed via cache-coherent portals, using ringbuffers as I/O. The intent is for portals to be per-CPU (core/thread)to reduce locking contention and improve performance. This driver pinsinterrupt handlers to the CPU "owning" a given portal, and uses criticalsections to prevent switching while accessing the portal.
