Both fiber and copper variants of +the cards are supported. +.Pp +The 82542 supports TBI (ten bit interface), while the 82543 supports the +GMII transceivers, which means it can be used with either copper or +1000baseX fiber applications. +Both boards support VLAN tagging/insertion and the 82543 additionally +supports TCP/IP checksum offload. +.Pp +The 82543-T cards use the Marvell 10/100/1000 copper gigabit tranceiver +chip, which supports autonegotiation of 10, 100 and 1000mbps modes in +full or half duplex, however half duplex 1000mbps is not suppoorted. +.Pp +The driver also supports jumbo frames, which can be configured +via the interface MTU setting. +Selecting an MTU larger than 1500 bytes with the +.Xr ifconfig 8 +utility configures the adapter to receive and transmit jumbo frames. +Using jumbo frames can greatly improve performance for certain tasks, +such as file transfers and data streaming. +.Pp +The +.Nm +driver supports the following media types: +.Bl -tag -width 10baseTXUTP +.It Cm autoselect +Enable autoselection of the media type and options. +The user can manually override +the autoselected mode by adding media options to +.Xr rc.conf 5 . +.It Cm 10baseT/UTP +Set 10Mbps operation. +The +.Xr ifconfig 8 +.Ic mediaopt +option can also be used to select either +.Cm full-duplex +or +.Cm half-duplex +modes. +.It Cm 100baseTX +Set 100Mbps (fast ethernet) operation. +The +.Xr ifconfig 8 +.Ic mediaopt +option can also be used to select either +.Cm full-duplex +or +.Cm half-duplex +modes. +.It Cm 1000baseTX +Set 1000baseTX operation over twisted pair. +Only +.Cm full-duplex +mode is supported. +.El +.Pp +The +.Nm +driver supports the following media options: +.Bl -tag -width full-duplex +.It Cm full-duplex +Force full duplex operation. +.It Cm half-duplex +Force half duplex operation. +.El +.Pp +The +.Nm +driver also supports one special link option for 1000baseTX cards: +.Bl -tag -width link0 +.It Cm link0 +With 1000baseTX cards, establishing a link between two ports requires +that one port be configured as a master and the other a slave. +With autonegotiation, +the master/slave settings should be chosen automatically. +Setting the +.Cm link0 +flag with +.Xr ifconfig 8 +will force the link up instead. +.El +.Pp +For more information on configuring this device, see +.Xr ifconfig 8 . +.Sh DIAGNOSTICS +.Bl -diag +.It "gx%d: couldn't map memory" +A fatal initialization error has occurred. +.It "gx%d: couldn't map interrupt" +A fatal initialization error has occurred. +.It "gx%d: couldn't setup irq" +A fatal initialization error has occurred. +.It "gx%d: failed to read station address" +A fatal initialization error has occurred. +.It "gx%d: no memory for list buffers!" +The driver failed to allocate memory for per-device instance information +during initialization. +.It "gx%d: failed to enable memory mapping!" +The driver failed to initialize PCI shared memory mapping. +This might happen if the card is not in a bus-master slot. +.It "gx%d: GMII/MII, PHY not detected" +The MII probe routines failed to detect the PHY. +This might happen if miibus is not configured. +.It "gx%d: watchdog timeout" +The device has stopped responding to the network, or there is a problem with +the network connection (cable). +.It "gx%d: mbuf allocation failed -- packet dropped" +The driver could not allocate a mbuf for the receive ring. +.It "gx%d: cluster allocation failed -- packet dropped" +The driver could not allocate a mbuf cluster for the receive ring. +.It "gx%d: link down" +The link status changed from up to down. +.It "gx%d: link up" +The link status changed from down to up. +.El +.Sh SEE ALSO +.Xr arp 4 , +.Xr netintro 4 , +.Xr ng_ether 4 , +.Xr vlan 4 , +.Xr ifconfig 8 +.Sh HISTORY +The +.Nm +device driver first appeared in +.Fx 4.5 . +.Sh AUTHORS +The +.Nm +driver was written by +.An Jonathan Lemon Aq jlemon@freebsd.org . |
