3c574_cs is the low-level Card Services driver for the 3Com 3c574
EtherLink XL PCMCIA ethernet adapter. When this driver is attached to
a card, it allocates the next available ethernet device (eth0..eth#).
This device name will be reported in the kernel log file, and passed on
The driver uses the N-Way autonegotiating transceiver to negotiate the
speed and duplex of the network link. If the link partner does not
support negotiation, only the link speed is detected.
Selects the PCMCIA debugging level. This parameter is only
available if the module is compiled with debugging enabled. A
non-zero value enables debugging.
Selects the transceiver type. Only 0, 1, and 4 are acceptable
values, other values return an error. This actual value speci-
ficed is ignored -- the autonegotiating transceiver selects the
media speed and duplex used.
This option limits the set of interrupts that may be allocated
by this driver. The default is all normally-usable IRQs.
This flag determines if only full-duplex modes are advertised.
It defaults to 0 (false).
This flag can be used to control the transceiver's auto polarity
detection capability. Some Cisco Catalyst switches are known to
interact badly with this feature in 10baseT mode. It defaults
to 1 (enabled).
This option selects the maximum amount of work handled during
each interrupt. Each received packet counts as one unit of
work, as does updating statistics counters and handling errors.
The default is 32.
eth#: interrupt(s) dropped!
Indicates that the driver did not receive an interrupt notifica-
tion for some reason. The driver will poll the card (with a
significant performance penalty) if the problem persists. The
most likely cause is an interrupt conflict and/or host bridge
This man page describes the standalone PCMCIA drivers provided by the
pcmcia-cs source, not the PCMCIA kernel driver support that is included
in the 2.4 (and later) linux kernel. While the kernel PCMCIA code has
the same functionality as the driver side of the standalone PCMCIA
package, there are some important differences. Therefore, some or all
of this documentation might not apply to the kernel drivers.
