.Sh NAME
|
|
.Nm fxp
|
|
.Nd device driver for Intel i82557 and i82558 Ethernet interfaces
|
|
.Sh SYNOPSIS
|
|
.Cd "fxp* at pci? dev ? function ?"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
Supported cards include the Intel EtherExpress Pro 10+, EtherExpress
|
|
Pro 100B, and EtherExpress Pro 100+.
|
|
.Sh MEDIA SELECTION
|
|
Media selection is supported via MII. See
|
|
.Xr ifmedia 4
|
|
and
|
|
.Xr mii 4
|
|
for more information.
|
|
.Pp
|
|
EtherExpress Pro 10+ boards may use a Seeq 80c24 AutoDUPLEX(tm)
|
|
media interface. 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).
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It "fxp0: WARNING: SCB timed out!"
|
|
The driver timed out waiting for the chip's command interface to
|
|
become ready.
|
|
.It "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.
|
|
.It "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.
|
|
.It "fxp0: can't load mbuf chain, error = %d"
|
|
The driver was unable to load a transmit DMA map, and has reported the
|
|
errno value.
|
|
.It "fxp0: device timeout"
|
|
The device failed to generate a transmit complete interrupt for the
|
|
last packet transmitted. The device has been reset.
|
|
.It "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 error is currently fatal, and will
|
|
panic the system.
|
|
.It "fxp0: fxp_mdi_read: timed out"
|
|
The MDIO failed to become ready during an MII read operation.
|
|
.It "fxp0: fxp_mdi_write: timed out"
|
|
The MDIO failed to become ready during an MII write operation.
