It is currently available only as a kernel module. The mgb device driver provides support for PCIe Gigabit Ethernet adapters based on Microchip's LAN7430 and LAN7431. For more information on configuring this device, see ifconfig(8). HARDWARE The mgb driver supports: • Microchip LAN7430 PCIe Gigabit Ethernet controller with PHY • Microchip LAN7431 PCIe Gigabit Ethernet controller with RGMII in- terface SEE ALSO arp(4), miibus(4), ifconfig(8) CAVEATS The driver does not yet implement support for many hardware features, including: • Multiple RX queue support • RX and TX checksum offload • Hardware VLAN tagging or untagging • Multicast receive packet filtering • Wake on LAN (WoL) • LSO • RSS LAN7431 support is completely untested.
