If you have a network (Ethernet) card belonging to this class, say Y.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about TI devices. If you say Y, you will be asked for
your specific card in the following questions.

net: ethernet: ti: cpsw: add XDP support Add XDP support based on rx page_pool allocator, one frame per page. Page pool allocator is used with assumption that only one rx_handler is running simultaneously. DMA map/unmap is reused from page pool despite there is no need to map whole page. Due to specific of cpsw, the same TX/RX handler can be used by 2 network devices, so special fields in buffer are added to identify an interface the frame is destined to. Thus XDP works for both interfaces, that allows to test xdp redirect between two interfaces easily. Also, each rx queue have own page pools, but common for both netdevs. XDP prog is common for all channels till appropriate changes are added in XDP infrastructure. Also, once page_pool recycling becomes part of skb netstack some simplifications can be added, like removing page_pool_release_page() before skb receive. In order to keep rx_dev while redirect, that can be somehow used in future, do flush in rx_handler, that allows to keep rx dev the same while redirect. It allows to conform with tracing rx_dev pointed by Jesper. Also, there is probability, that XDP generic code can be extended to support multi ndev drivers like this one, using same rx queue for several ndevs, based on switchdev for instance or else. In this case, driver can be modified like exposed here: https://lkml.org/lkml/2019/7/3/243 Acked-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S.

net: netcp: Add Keystone NetCP core ethernet driver The network coprocessor (NetCP) is a hardware accelerator available in Keystone SoCs that processes Ethernet packets. NetCP consists of following hardware components 1 Gigabit Ethernet (GbE) subsystem with a Ethernet switch sub-module to send and receive packets. 2 Packet Accelerator (PA) module to perform packet classification operations such as header matching, and packet modification operations such as checksum generation. 3 Security Accelerator(SA) capable of performing IPSec operations on ingress/egress packets. 4 An optional 10 Gigabit Ethernet Subsystem (XGbE) which includes a 3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates per Ethernet port. 5 Packet DMA and Queue Management Subsystem (QMSS) to enqueue and dequeue packets and DMA the packets between memory and NetCP hardware components described above. NetCP core driver make use of the Keystone Navigator driver API to allocate DMA channel for the Ethenet device and to handle packet queue/de-queue, Please refer API's in include/linux/soc/ti/knav_dma.h and drivers/soc/ti/knav_qmss.h for details. NetCP driver consists of NetCP core driver and at a minimum Gigabit Ethernet (GBE) module (1) driver to implement the Network device function. Other modules (2,3) can be optionally added to achieve supported hardware acceleration function. The initial version of the driver include NetCP core driver and GBE driver modules. Please refer Documentation/devicetree/bindings/net/keystone-netcp.txt for design of the driver.
