37.Nm vx
38.Nd 3Com EtherLink III / Fast EtherLink III (3c59x) Ethernet driver
39.Sh SYNOPSIS
40.Cd "device vx"
41.Sh DESCRIPTION
42The
43.Nm
44driver provides support for the 3Com
45.Dq Vortex
46chipset.
47.Pp
48The medium selection
49can be influenced by the following link flags to the
50.Xr ifconfig 8
51command:
52.Pp
53.Bl -tag -width LINK0X -compact
54.It Em link0
55Use the AUI port.
56.It Em link1
57Use the BNC port.
58.It Em link2
59Use the UTP port.
60.El
61.Sh HARDWARE
62The
63.Nm
64driver supports the following cards:
65.Pp
66.Bl -bullet -compact
67.It
683Com 3c590 EtherLink III PCI
69.It
703Com 3c592 EtherLink III EISA
71.It
723Com 3c595 Fast EtherLink III PCI in 10 Mbps mode
73.It
743Com 3c597 Fast EtherLink III EISA in 10 Mbps mode
75.El
76.Sh DIAGNOSTICS
77.Bl -diag
78.It "vx%d: not configured; kernel is built for only %d devices."
79There are not enough devices in the kernel configuration file for the number
80of adapters present in the system.
81Add devices to the configuration file,
82rebuild the kernel, and reboot.
83.El
84.Pp
85All other diagnostics indicate either a hardware problem or a bug in the
86driver.
87.Sh CAVEATS
88Some early-revision 3c590 cards are defective and suffer from many receive
89overruns, which cause lost packets.
90The author has attempted to implement
91a test for it based on the information supplied by 3Com, but the test resulted
92mostly in spurious warnings.
93.Pp
94The performance of this driver is somewhat limited by the fact that it uses
95only polled-mode I/O and does not make use of the bus-mastering capability
96of the cards.

102.Sh HISTORY
103The
104.Nm
105device driver first appeared in
106.Fx 2.1 .
107It was derived from the
108.Nm ep
109driver, from which it inherits most of its limitations.

112The

114device driver and this manual page were written by
115.An Fred Gray Aq fgray@rice.edu ,
116based on the work of
117.An Herb Peyerl
118and with the assistance of numerous others.
119.Sh BUGS
120The
121.Nm
122driver is known not to reset the adapter correctly following a warm boot
123on some systems.
124.Pp
125The
126.Nm
127driver has not been exhaustively tested with all the models of cards that it
128claims to support.
