Subject: [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 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/
