50.Sh DESCRIPTION
51The
52.Nm
53driver provides support for the Ethernet adapters based on the
54SMC 83c17x (EPIC) chips.
55These are mostly SMC 9432 series cards.
56.Pp
57The
58.Nm
59driver supports the following media types (depending on card's capabilities):
60.Pp
61.Bl -tag -width ".Cm 10baseT/UTP"
62.It Cm autoselect
63Enable autonegotiation (default).
64.It Cm 100baseFX
65Set 100Mbps (Fast Ethernet) fiber optic operation.
66.It Cm 100baseTX
67Set 100Mbps (Fast Ethernet) twisted pair operation.
68.It Cm 10baseT/UTP
69Set 10Mbps on 10baseT port.
70.It Cm 10base2/BNC
71Set 10Mbps on 10base2 port.
72.El
73.Pp
74The
75.Nm
76driver supports the following media options:
77.Bl -tag -width ".Cm full-duplex"
78.It Cm full-duplex
79Set full-duplex operation.
80.El
81.Pp
82The
83.Nm
84driver supports oversized Ethernet packets (up to 1600 bytes).
85Refer to the
86.Xr ifconfig 8
87man page on setting the interface's MTU.
88.Pp
89The old
90.Dq Li "ifconfig tx0 linkN"
91method of configuration is not supported.
92.Ss "VLAN (IEEE 802.1Q) support"
93The
94.Nm
95driver supports the VLAN operation (using
96.Xr vlan 4
97interfaces) without decreasing the MTU on the
98.Xr vlan 4
99interfaces.
100.Sh DIAGNOSTICS
101.Bl -diag
102.It "tx%d: device timeout %d packets"
103The device stops responding.
104Device and driver reset follows this error.
105.It "tx%d: PCI fatal error occurred (%s)"
106One of following errors occurred: PCI Target Abort, PCI Master Abort, Data
107Parity Error or Address Parity Error.
108Device and driver reset follows this error.
109.It "tx%d: cannot allocate mbuf header/cluster"
110Cannot allocate memory for received packet.
111Packet thrown away.
112.It "tx%d: can't stop %s DMA"
