SMC9432TX Fast Ethernet device driver
.Sh SYNOPSIS
.Cd "device tx0"
.Sh DESCRIPTION
The
.Nm
driver provides support for the Ethernet adapters based on the
SMC 83c170 (EPIC) chips.
.Pp
The
.Nm
driver supports the following media types:
.Pp
.Bl -tag -width xxxxxxxxxxxxxxx
.It autoselect
Enable autonegotiation (default)
.It 100baseTX
Set 100Mbps (fast ethernet) operation
.It 10baseT/UTP
Set 10Mbps on 10baseT port
.El
.Pp
The
.Nm
driver supports the following media options:
.Pp
.Bl -tag -width xxxxxxxxxxxxxxx
.It full-duplex
Set full-duplex operation
.El
.Pp
The old ``ifconfig tx0 linkN'' method of configuration is not supported.
.Sh DIAGNOSTICS
.Bl -diag
.It "tx%d: device timeout %d packets"
The device stops responding. Device and driver reset follows this error.
.It "tx%d: PCI fatal error occured (%s)"
One of following errors occured: PCI Target Abort, PCI Master Abort, Data
Parity Error or Address Parity Error. Device and driver reset follows this error.
.It "tx%d: WARNING! no link established"
No media connected. Displayed at startup only.
.It "tx%d: cannot allocate mbuf header/cluster"
Cannot allocate memory for received packet. Packet thrown away.
.It "tx%d: can't stop %s DMA"
While reseting, driver failed to stop device correctly.

.Sh BUGS
.Pp
The multicast packets filtering is not supported.
Only one PHY was really tested (Quality Semiconductor QS6612).
