^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 3) The PIP Ethernet nexus can control several data packet input/output
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 4) devices. The devices have a two level grouping scheme. There may be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 5) several interfaces, and each interface may have several ports. These
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 6) ports might be an individual Ethernet PHY.
