NAME
fxp - Intel i82557, i82558, and i82559 Ethernet interfaces device driver
SYNOPSIS
fxp* at cardbus? dev ? function ? fxp* at pci? dev ? function ?
DESCRIPTION
The fxp device driver supports Ethernet interfaces based on the Intel i82557 and i82558 PCI Ethernet chips. The i82557 uses an external media interface, whereas the i82558 includes a built-in Intel i82555 PHY. The i82559 is an enhanced i82558.
HARDWARE
Cards supported by the fxp driver include: Intel EtherExpress Pro 10+ Intel EtherExpress Pro 100B Intel EtherExpress Pro 100+
MEDIA SELECTION
Media selection is supported via MII. See ifmedia(4) and mii(4) for more information. EtherExpress Pro 10+ boards may use a Seeq 80c24 AutoDUPLEX(tm) media in- terface. Boards with these chips do not support media selection, as the 80c24 has no programming interface, and no way to read link status. These boards claim a media of "manual" since they self-configure based on the configuration of the link partner (hub or switch).
DIAGNOSTICS
fxp0: WARNING: SCB timed out! The driver timed out waiting for the chip's command interface to become ready. fxp0: too many segments, aborting The driver encountered a packet that included too many DMA segments, and was not able to allocate a new buffer to transmit the packet from. The packet has been dropped. fxp0: too many segments, retrying The driver encountered a packet that included too many DMA segments, and allocated a new buffer to transmit the packet from. fxp0: can't load mbuf chain, error = %d The driver was unable to load a transmit DMA map, and has reported the errno value. fxp0: device timeout The device failed to generate a transmit complete interrupt for the last packet transmitted. The device has been reset. fxp0: can't load rx buffer, error = %d The driver was unable to load the DMA map for a receive buffer, and has reported the errno value. This er- ror is currently fatal, and will panic the system. fxp0: fxp_mdi_read: timed out The MDIO failed to become ready during an MII read operation. fxp0: fxp_mdi_write: timed out The MDIO failed to become ready during an MII write operation.
