.Sh NAME
.Nm el
.Nd Ethernet driver for 3Com Etherlink 3C501 device driver
.Sh SYNOPSIS
.Cd "device el"
.Pp
In
.Pa /boot/device.hints :
.Cd hint.el.0.at="isa"
.Cd hint.el.0.port="0x300"
.Cd hint.el.0.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.
