tsnep: Support XDP BPF program setup

2023-01-18T13:17:06Z

Implement setup of BPF programs for XDP RX path with command XDP_SETUP_PROG of ndo_bpf(). This is the final step for XDP RX path support. There is no need to reinit the RX queues as they are always prepared for XDP. Additionally remove $(tsnep-y) from $(tsnep-objs) because it is added automatically. Test results with A53 1.2GHz: XDP_DROP (samples/bpf/xdp1) proto 17: 883878 pkt/s XDP_TX (samples/bpf/xdp2) proto 17: 255693 pkt/s XDP_REDIRECT (samples/bpf/xdpsock) sock0@eth2:0 rxdrop xdp-drv pps pkts 1.00 rx 855,582 5,404,523 tx 0 0 XDP_REDIRECT (samples/bpf/xdp_redirect) eth2->eth1 613,267 rx/s 0 err,drop/s 613,272 xmit/s Signed-off-by: Gerhard Engleder Signed-off-by: David S.

tsnep: Add EtherType RX flow classification support

2022-09-30T10:32:27Z

Received Ethernet frames are assigned to first RX queue per default. Based on EtherType Ethernet frames can be assigned to other RX queues. This enables processing of real-time Ethernet protocols on dedicated RX queues. Add RX flow classification interface for EtherType based RX queue assignment.

tsnep: Add TSN endpoint Ethernet MAC driver

2021-11-22T13:19:04Z

The TSN endpoint Ethernet MAC is a FPGA based network device for real-time communication. It is integrated as Ethernet controller with ethtool and PTP support. For real-time communcation TC_SETUP_QDISC_TAPRIO is supported. Signed-off-by: Gerhard Engleder Signed-off-by: David S. Miller
