.. title:: NET_PKT_TXTIME_STATS

.. option:: CONFIG_NET_PKT_TXTIME_STATS

*Enable network packet TX time statistics*

Type: ``bool``

Help
====

Enable network packet TX time statistics support. This is used to
calculate how long on average it takes for a packet to travel from
application to just before it is sent to network. The TX timing
information can then be seen in network interface statistics in
net-shell.
The RX calculation is done only for UDP, TCP or RAW packets,
but for TX we do not know the protocol so the TX packet timing is
done for all network protocol packets.
