NAME
       mgb -- Microchip	LAN743x	PCIe Gigabit Ethernet driver

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 limita-
       tions.  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.
