+.Sh DESCRIPTION
+The
+.Nm
+device driver supports the Intel EtherExpress 100 family of Ethernet cards
+based on various revisions of the i82557, i82558, i82559, i82559S,
+i82550, i82551, and i82562 chipsets, including the following:

+The following media types and options (as given to
+.Xr ifconfig 8 )
+are supported:
+.Bl -tag -width xxx -offset indent
+.It Cm media No autoselect
+Enable autoselection of the media type and options (default).
+.It Cm media No 100baseTX Cm mediaopt No full-duplex
+Set 100Mbps (Fast Ethernet) operation and force full-duplex mode.
+.It Cm media No 100baseTX Cm mediaopt No half-duplex
+Set 100Mbps (Fast Ethernet) operation and force half-duplex mode.
+.It Cm media No 10baseT Cm mediaopt No full-duplex
+Set 10Mbps operation and force full-duplex.
+.It Cm media No 10baseT Cm mediaopt No half-duplex
+Set 10Mbps operation and force half-duplex.
+.El
+.Pp
+If no media options are present, the
+.Nm
+driver places the card into autoselect mode.
+.Sh FILES
+Some devices are able to do interrupt coalescing but it requires firmware
+updating.
+The following firmware files are potentially loaded on demand when an
+interface is brought up:
+.Pp
+.Bl -tag -width Ds -offset indent -compact
+.It Pa /etc/firmware/fxp-d101a

+.It Pa /etc/firmware/fxp-d102c
+.It Pa /etc/firmware/fxp-d102e
+.El
+.Pp
+If a file is missing, the driver attempts to operate anyway.
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "fxp0: couldn't map memory"
+A fatal initialization error has occurred.
+.It "fxp0: couldn't map interrupt"
