tx -- SMC 83c17x Fast Ethernet device driver
The tx driver provides support for the Ethernet adapters based on the SMC
83c17x (EPIC) chips. These are mostly SMC 9432 series cards.
The tx driver supports the following media types (depending on card's
autoselect Enable autonegotiation (default).
100baseFX Set 100Mbps (Fast Ethernet) fiber optic operation.
100baseTX Set 100Mbps (Fast Ethernet) twisted pair operation.
10baseT/UTP Set 10Mbps on 10baseT port.
10base2/BNC Set 10Mbps on 10base2 port.
The tx driver supports the following media options:
full-duplex Set full-duplex operation.
The tx driver supports oversized Ethernet packets (up to 1600 bytes).
Refer to the ifconfig(8) man page on setting the interface's MTU.
The old ``ifconfig tx0 linkN'' method of configuration is not supported.
VLAN (IEEE 802.1Q) support
The tx driver supports the VLAN operation (using vlan(4) interfaces)
without decreasing the MTU on the vlan(4) interfaces.
tx%d: device timeout %d packets The device stops responding. Device and
driver reset follows this error.
tx%d: PCI fatal error occurred (%s) One of following errors occurred:
PCI Target Abort, PCI Master Abort, Data Parity Error or Address Parity
Error. Device and driver reset follows this error.
tx%d: cannot allocate mbuf header/cluster Cannot allocate memory for
received packet. Packet thrown away.
tx%d: can't stop %s DMA While resetting, the driver failed to stop the
The auto-negotiation does not work very well.
