Add support to configure a new client as Ethernet type over MHI by
setting "mhi_device_info.ethernet_if = true". Create a new Ethernet
interface named eth%d. This complements existing NET driver support.
Introduce IP_SW1, ETH0, and ETH1 network interfaces required for
M-plane, NETCONF, and S-plane components.
M-plane:
Implement DU M-Plane software for non-real-time O-RAN management
between O-DU and O-RU using NETCONF/YANG and O-RAN WG4 M-Plane YANG
models. Provide capability exchange, configuration management,
performance monitoring, and fault management per O-RAN.WG4.TS.MP.0-
R004-v18.00.
Netconf:
Use NETCONF protocol for configuration operations such as fetching,
modifying, and deleting network device configurations.
S-plane:
Support frequency and time synchronization between O-DUs and O-RUs
using Synchronous Ethernet and IEEE 1588. Assume PTP transport over
L2 Ethernet (ITU-T G.8275.1) for full timing support; allow PTP over
UDP/IP (ITU-T G.8275.2) with reduced reliability. as per ORAN spec
O-RAN.WG4.CUS.0-R003-v12.00.

S-plane: To support accurate phase and time synchronization between the host (L2) and device (L1‑High), the system must exchange PTP messages as raw Layer‑2 Ethernet frames, because the ITU‑T G.8275.1 profile operates strictly over Ethernet multicast and not over IP networks. This means the device’s PTP stack can only send and receive PTP Announce, Sync, Follow‑Up, and Delay messages in native Ethernet format, not as IPv4/IPv6 packets. However, the host and device communicate only through MHI/PCIe, which provides no native Ethernet interface. Therefore, the system must implement a virtual Ethernet interface over MHI on both sides. This virtual Layer‑2 link enables true Ethernet‑frame transport, ensuring the device’s PTP implementation remains fully compliant with the G.8275.1 Ethernet‑based timing model -Vivek >> Signed-off-by: Vivek Pernamitta <vivek.pernamitta@oss.qualcomm.com> >> --- >> patchset link for V5 : https://lore.kernel.org/all/20251106-vdev_next-20251106_eth-v5-0-bbc0f7ff3a68@quicinc.com/ >> patchset link for V1 (first post) : https://lore.kernel.org/all/20250724-b4-eth_us-v1-0-4dff04a9a128@quicinc.com/ >> >> changes to v6: >> - Removed interm variable useage as per comments from Simon and Dmirty. >> - Squashed gerrits 1 and 2 in single gerrit. >> - Added more description for M-plane, Netconf and S-plane. >> >> changes to v5: >> - change in email ID from "quic_vpernami@quicinc.com" to "vivek.pernamitta@oss.qualcomm.com" >> - Renamed to patch v5 as per comments from Manivannan >> - Restored to original name as per comments from Jakub >> - Renamed the ethernet interfce to eth%d as per Jakub >> --- >> >> --- >> Vivek Pernamitta (2): >> net: mhi: Enable Ethernet interface support >> bus: mhi: host: pci: Enable IP_SW1, IP_ETH0 and IP_ETH1 channels for QDU100 >> >> drivers/bus/mhi/host/pci_generic.c | 8 ++++ >> drivers/net/mhi_net.c | 75 +++++++++++++++++++++++++++++++------- >> 2 files changed, 70 insertions(+), 13 deletions(-) >> --- >> base-commit: 82bcd04d124a4d84580ea4a8ba6b120db5f512e7 >> change-id: 20251209-vdev_next-20251208_eth_v6-c405aed13fed >> >> Best regards, >> -- >> Vivek Pernamitta <<quic_vpernami@quicinc.com>> >> >
