+if the socket does not have SO_TXTIME socket option set. But, this will not
+work if the launchtime is set by another entity inside the kernel (e.g. some

+Specifies different modes for taprio. Currently, only txtime-assist is
+supported which can be enabled by setting it to 0x1. In this mode, taprio will
+set the transmit timestamp depending on the interval in which the packet needs

+This parameter is specific to the txtime offload mode. It specifies the maximum
