Currently, user needs to manually enable transmit hardware timestamp
feature of certain Ethernet drivers, e.g. stmmac and igc drivers, through
following command after running the xdp_hw_metadata app.

sudo hwstamp_ctl -i eth0 -t 1

To simplify the step test of xdp_hw_metadata, set tx_type to HWTSTAMP_TX_ON
to enable hardware timestamping for all outgoing packets, so that user no
longer need to execute hwstamp_ctl command.

v1: https://patchwork.kernel.org/project/netdevbpf/patch/20241204115715.3148412-1-yoong.siang.song@intel.com/

v1->v2 changelog:
 - Add detail in commit msg on why HWTSTAMP_TX_ON is needed (Stanislav).
 - Separate the patch into two, current one submit to bpf-next,
   another one submit to bpf.
