NAME

     wm - Intel i8254x Gigabit Ethernet driver


SYNOPSIS

     wm* at pci? dev ? function ?

     Configuration of PHYs may also be necessary.  See mii(4).


DESCRIPTION

     The wm device driver supports Gigabit Ethernet interfaces based on the
     Intel i8254x family of Gigabit Ethernet chips.  The interfaces supported
     by the wm driver include:

     +   Intel i82542 1000BASE-X Ethernet

     +   Intel i82543GC 1000BASE-X Ethernet

     +   Intel i82543GC 1000BASE-T Ethernet

     +   Intel i82544EI 1000BASE-T Ethernet

     +   Intel i82544EI 1000BASE-X Ethernet

     +   Intel i82544GC 1000BASE-T Ethernet

     +   Intel i82544GC (LOM) 1000BASE-T Ethernet

     +   Intel i82540EM 1000BASE-T Ethernet

     +   Intel i82545EM 1000BASE-T Ethernet

     +   Intel i82546EB 1000BASE-T Ethernet (dual-port)

     +   Intel i82545EM 1000BASE-X Ethernet

     +   Intel i82546EB 1000BASE-X Ethernet (dual-port)

     +   Intel i82540EM (LOM) 1000BASE-T Ethernet

     In addition to Intel's own ``PRO/1000'' line of Gigabit Ethernet inter-
     faces, these chips also appear on some server systems, processor evalua-
     tion boards, and in embedded systems.

     The i8254x supports IPv4/TCP/UDP checksumming in hardware.  The wm driver
     supports this feature of the chip.  See ifconfig(8) for information on
     how to enable this feature.
