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 i82540EM (LOM) 1000BASE-T Ethernet

     ·   Intel i82540EP 1000BASE-T Ethernet

     ·   Intel i82541EI 1000BASE-T Ethernet

     ·   Intel i82541EI (Mobile) 1000BASE-T Ethernet

     ·   Intel i82541ER 1000BASE-T Ethernet

     ·   Intel i82541GI 1000BASE-T Ethernet

     ·   Intel i82541PI 1000BASE-T Ethernet

     ·   Intel i82545EM 1000BASE-T Ethernet

     ·   Intel i82545EM 1000BASE-X Ethernet

     ·   Intel i82545GB 1000BASE-T Ethernet

     ·   Intel i82545GB 1000BASE-X Ethernet

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

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

     ·   Intel i82546GB 1000BASE-T Ethernet (dual-port)

     ·   Intel i82546GB 1000BASE-X Ethernet (dual-port)

     ·   Intel i82547EI 1000BASE-T Ethernet (CSA)

     ·   Intel i82547GI 1000BASE-T Ethernet (CSA)

     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 and TCP segmentation in
     hardware.  The wm driver supports these features of the chip.  See
     ifconfig(8) for information on how to enable this feature.

BUGS

     The Intel i82545GM and i82546GB controllers with internal SERDES are not
     currently supported.
