^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) When the kernel has several packets to send out over a network
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) device, it has to decide which ones to send first, which ones to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) delay, and which ones to drop. This is the job of the queueing
