.Sh NAME
|
|
.Nm el
|
|
.Nd Ethernet driver for 3Com Etherlink 3C501 device driver
|
|
.Sh SYNOPSIS
|
|
.Cd "device el0 at isa? port 0x300 irq 9"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
interface provides support for the 3Com 3c501 8bit ISA ethernet card.
|
|
The 3c501 card is known to be quite slow, and a different ethernet card
|
|
should be used if possible.
|
|
However, they allow inexpensive access to 10 Mb/s Ethernet networks.
|
|
.Pp
|
|
The valid I/O ports are in the range 0x280-0x3f0.
|
|
.Sh BUGS
|
|
The driver assumes the card is configured for the same IRQ as the kernel.
|
|
No probing or checking is done to determine if this is the case.
|
|
.Pp
|
|
Does not currently support DMA.
|
|
.Pp
|
|
Does not currently support multicasts.
