title: Loongson-1C Ethernet MAC Controller

maintainers:
  - Keguang Zhang <keguang.zhang@gmail.com>

description: |
  Loongson-1C Ethernet MAC Controller is based on
  Synopsys DesignWare MAC (version 3.50a).

  Main features
  - 10/100Mbps
  - Full-duplex operation (IEEE 802.3x flow control automatic transmission)
  - Half-duplex operation (CSMA/CD Protocol and back-pressure support)
  - IEEE 802.1Q VLAN tag detection for reception frames
  - MII interface
  - RMII interface

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
