The i82557 uses an external media 52interface, whereas the i82558 includes a built-in Intel i82555 PHY. 53The i82559 is an enhanced i82558. 54.Pp 55.Sh HARDWARE 56Cards supported by the 57.Nm 58driver include: 59.Pp 60.Bl -item -compact 61.It 62Intel EtherExpress Pro 10+ 63.It 64Intel EtherExpress Pro 100B 65.It 66Intel EtherExpress Pro 100+ 67.It 68Intel PRO/100 S 69.El 70.Sh MEDIA SELECTION 71Media selection is supported via MII. See 72.Xr ifmedia 4 73and 74.Xr mii 4 75for more information. 76.Pp 77EtherExpress Pro 10+ boards may use a Seeq 80c24 AutoDUPLEX(tm) 78media interface. Boards with these chips do not support media 79selection, as the 80c24 has no programming interface, and no 80way to read link status. These boards claim a media of "manual" 81since they self-configure based on the configuration of the link 82partner (hub or switch). 83.Sh DIAGNOSTICS 84.Bl -diag 85.It "fxp0: WARNING: SCB timed out!" 86The driver timed out waiting for the chip's command interface to 87become ready. 88.It "fxp0: too many segments, aborting" 89The driver encountered a packet that included too many DMA segments, 90and was not able to allocate a new buffer to transmit the packet from. 91The packet has been dropped. 92.It "fxp0: too many segments, retrying" 93The driver encountered a packet that included too many DMA segments, 94and allocated a new buffer to transmit the packet from. 95.It "fxp0: can't load mbuf chain, error = %d" 96The driver was unable to load a transmit DMA map, and has reported the 97errno value. 98.It "fxp0: device timeout" 99The device failed to generate a transmit complete interrupt for the 100last packet transmitted. The device has been reset. 101.It "fxp0: can't load rx buffer, error = %d" 102The driver was unable to load the DMA map for a receive buffer, and 103has reported the errno value. This error is currently fatal, and will 104panic the system. 105.It "fxp0: fxp_mdi_read: timed out" 106The MDIO failed to become ready during an MII read operation. 107.It "fxp0: fxp_mdi_write: timed out" 108The MDIO failed to become ready during an MII write operation. 109.El 110.Sh SEE ALSO 111.Xr cardbus 4 , 112.Xr ifmedia 4 , 113.Xr intro 4 , 114.Xr mii 4 , 115.Xr pci 4 , 116.Xr ifconfig 8 117
