SYNOPSIS
To load the driver as a module at boot time, place the following line in
loader.conf(5):
if_mgb_load="YES"
DESCRIPTION
The mgb driver is experimental, and has a number of caveats and
limitations. 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:
o Microchip LAN7430 PCIe Gigabit Ethernet controller with PHY
o Microchip LAN7431 PCIe Gigabit Ethernet controller with RGMII
interface
SEE ALSO
arp(4), miibus(4), ifconfig(8)
CAVEATS
The driver does not yet implement support for many hardware features,
including:
o Multiple RX queue support
o RX and TX checksum offload
o Hardware VLAN tagging or untagging
o Multicast receive packet filtering
o Wake on LAN (WoL)
o LSO
o RSS
LAN7431 support is completely untested.
