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.

Direct dependencies¶

(NET_UDP || NET_TCP || NET_SOCKETS_PACKET) && NET_NATIVE && NETWORKING

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
