38.Nd 3Com EtherLink III / Fast EtherLink III (3c59x) Ethernet driver
| 38.Nd "3Com EtherLink III / Fast EtherLink III (3c59x) Ethernet driver"
|
39.Sh SYNOPSIS
| 39.Sh SYNOPSIS
|
| 40To compile support for the
41.Nm
42driver into your kernel, place the following liness in your kernel configuration file:
43.Bd -ragged -offset indent
|
40.Cd "device vx"
| 44.Cd "device vx"
|
| 45.Ed
46.Pp
47Alternatively, to load the
48.Nm
49driver at boot time, place the following line in
50.Xr loader.conf 5 :
51.Bd -literal -offset indent
52if_vx_load="YES"
53.Ed
|
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.
