WM(4) BSD Kernel Interfaces Manual WM(4) 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 sup- ported by the wm driver include: o Intel i82542 1000BASE-X Ethernet o Intel i82543GC 1000BASE-X Ethernet o Intel i82543GC 1000BASE-T Ethernet o Intel i82544EI 1000BASE-T Ethernet o Intel i82544EI 1000BASE-X Ethernet o Intel i82544GC 1000BASE-T Ethernet o Intel i82544GC (LOM) 1000BASE-T Ethernet o Intel i82540EM 1000BASE-T Ethernet o Intel i82540EM (LOM) 1000BASE-T Ethernet o Intel i82540EP 1000BASE-T Ethernet o Intel i82541EI 1000BASE-T Ethernet o Intel i82541EI (Mobile) 1000BASE-T Ethernet o Intel i82541ER 1000BASE-T Ethernet o Intel i82541GI 1000BASE-T Ethernet o Intel i82541PI 1000BASE-T Ethernet o Intel i82545EM 1000BASE-T Ethernet o Intel i82545EM 1000BASE-X Ethernet o Intel i82545GB 1000BASE-T Ethernet o Intel i82545GB 1000BASE-X Ethernet o Intel i82545GM 1000BASE-T Ethernet o Intel i82546EB 1000BASE-T Ethernet (dual-port) o Intel i82546EB 1000BASE-X Ethernet (dual-port) o Intel i82546GB 1000BASE-T Ethernet (dual-port) o Intel i82546GB 1000BASE-X Ethernet (dual-port) o Intel i82547EI 1000BASE-T Ethernet (CSA) o Intel i82547GI 1000BASE-T Ethernet (CSA) o Intel i82571 1000BASE-T Ethernet (dual-port) o Intel i82572 1000BASE-T Ethernet o Intel i82573 1000BASE-T Ethernet o Intel i82575 1000BASE-T Ethernet o Intel i82576 Ethernet (Copper, Fiber) o Intel i80003 Ethernet (Copper, Fiber) o Intel i82801H (ICH8 LAN) 1000BASE-T Ethernet o Intel i82801I (ICH9 LAN) 1000BASE-T Ethernet o Intel i82801J (ICH10 LAN) 1000BASE-T Ethernet o Intel 82578 with Intel 5 series chipset (PCH) o Intel 82579 with Intel 6 or 7 series chipset (PCH2) o Intel 82580 Ethernet (Copper, Fiber) o Intel 82583 1000BASE-T Ethernet o Intel I350 Ethernet (Copper, Fiber) In addition to Intel's own ``PRO/1000'' line of Gigabit Ethernet interfaces, these chips also appear on some server systems, processor evalu- ation 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.
