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.
