[PATCH bpf-next v3 0/3] xsk: TX metadata Launch Time support

This series expands XDP TX metadata framework to include ETF HW offload. Changes since v1: (Willem) - rename Time-Based Scheduling (TBS) to Earliest TxTime First (ETF) - rename launch-time to txtime Changes since v2: (Jesper & Willem) - rename to use launch time - change the default launch time i

[PATCH bpf-next v3 1/3] xsk: add Launch Time HW offload to XDP Tx metadata

This patch extends the XDP Tx metadata framework so that user can requests Launch Time hardware offload, where the NIC will schedule the packet for transmission at a pre-determined time called launch time. The value of launch time is communicated from user space to Ethernet driver via launch_time f

[PATCH bpf-next v3 3/3] selftests/bpf: add Launch Time request to xdp_hw_metadata

This patch adds Launch Time hw offload request to xdp_hw_metadata. User can configure the delta of HW launch time to HW RX-time by using "-l" argument. The default delta is set to 0.1 second. This patch is tested with stmmac on Intel Tiger Lake platform. Refer to result below, the delta between pr
