Hi Wei,
The change loosk good to me, thanks!
I queued the patch for futher reviews and tests with some changes in the
commit log (for title formating and a bit more explanation), please see

Enable launch time (Time-Based Scheduling) support for XDP zero copy via

This patch has been tested with tools/testing/selftests/bpf/xdp_hw_metadata

Test 1: Send a single packet with the launch time
Add launch time hardware offload request to xdp_hw_metadata. Users can
configure the delta of launch time relative to HW RX-time using the "-l"
argument. By default, the delta is set to 0 ns, which means the launch time
is disabled. By setting the delta to a non-zero value, the launch time

Extend the XDP Tx metadata framework so that user can requests launch time
hardware offload, where the Ethernet device 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
This series expands the XDP TX metadata framework to allow user
applications to pass per packet 64-bit launch time directly to the kernel
driver, requesting launch time hardware offload support. The XDP TX
metadata framework will not perform any clock conversion or packet
reordering.
