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 in xdp_hw_metadata apps from 1s to 0.1s
  because some NICs do not support such a large future time.

v1: https://patchwork.kernel.org/project/netdevbpf/cover/20231130162028.852006-1-yoong.siang.song@intel.com/
v2: https://patchwork.kernel.org/project/netdevbpf/cover/20231201062421.1074768-1-yoong.siang.song@intel.com/

Song Yoong Siang (3):
  xsk: add Launch Time HW offload to XDP Tx metadata
  net: stmmac: add Launch Time support to XDP ZC
  selftests/bpf: add Launch Time request to xdp_hw_metadata
