|
|
.Cd "device fe 1"
|
|
.Pp
|
|
In
|
|
.Pa /boot/device.hints :
|
|
.Cd hint.fe.0.at="isa"
|
|
.Cd hint.fe.0.port="0x300"

.Cd hint.fe.0.flags="0x0"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
is a network device driver
|
|
for Ethernet adapters based on Fujitsu MB86960A, MB86965A,
|
|
or other compatible chips.
|
|
.Pp
|
|
The driver provides automatic I/O port address configuration and
|
|
automatic IRQ configuration,
|
|
when used with suitable adapter hardware.
|
|
.Pp
|
|
The driver works with program I/O data transfer technique.
|
|
It gives a fair performance.
|
|
Shared memory is never used, even if the adapter has one.
|
|
.Pp
|
|
It currently works with Fujitsu FMV-180 series for ISA,
|
|
Allied-Telesis AT1700 series and RE2000 series for ISA,
|
|
and Fujitsu MBH10302 PC card.
|
|
.Ss Parameters
|
|
In the
|
|
.Pa /boot/device.hints
|
|
file, two parameters,
|
|
.Ar port
|
|
and
|
|
.Ar irq ,
|
|
must be specified to reflect adapter hardware settings.
|
|
Another parameter
|
|
.Ar flags
|
|
can be specified to provide additional configuration as an option.
|
|
.Pp
|
|
The
|
|
.Ar port
|
|
parameter specifies a base I/O port address of the adapter.
|
|
It must match with the hardware setting of the adapter.
|
|
The
|
|
.Ar port
|
|
may be left unspecified by removing
|
|
.Dl hint.fe.0.port="..."
|
|
from the file.
|
|
In that case, the driver tries to detect the hardware setting
|
|
of the I/O address automatically.
|
|
This feature may not work with some adapter hardware.
|
|
.Pp
|
|
The
|
|
.Ar irq
|
|
parameter specifies an IRQ number used by the adapter.
|
|
It must match the hardware setting of the adapter.
|
|
.Ar Irq
|
|
may be left unspecified by removing
|
|
.Dl hint.fe.0.irq="..."
|
|
from the file.
|
|
in that case, the driver tries to detect
|
|
the hardware setting of the IRQ automatically.
|
|
This feature may not work on some adapters.
|
|
.Pp
|
|
The
|
|
.Ar flags
|
|
is a numeric value which consists of a combination of various device settings.
|
|
The following flags are defined in the current version.
|
|
To specify two or more settings for a device,
|
|
use a numeric sum of each flag value.
|
|
Flag bits not specified below are reserved and must be set to 0.
|
|
Actually, each bit is either just ignored by the driver,
|
|
or tested and used to control undocumented features of the driver.
|
|
Consult the source program for undocumented features.
|
|
.Bl -tag -width 8n
|
|
.It Li 0x007F
|
|
These flag bits are used
|
|
to initialize DLCR6 register of MB86960A/MB86965A chip,
|
|
when the
|
|
.Li 0x0080
|
|
bit of the
|
|
.Ar flags
|
|
is set.
|
|
See below for more about DLCR6 override feature.
|
|
The
|
|
.Li 0x007F
|
|
flag bits must be 0 unless the
|
|
.Li 0x0080
|
|
bit is set,
|
|
to maintain the compatibility with future versions of the driver.
|
|
.It Li 0x0080
|
|
This flag overrides the default setting to the DLCR6 register
|
|
of MB86960A/MB86965A chip by a user supplied value,
|
|
which is taken from the lower 7 bits of the flag value.
|
|
This is a troubleshooting flag and should not be used
|
|
without understanding of the adapter hardware.
|
|
Consult the Fujitsu manual for more information
|
|
on DLCR6 settings.
|
|
.El
|
|
.Sh OPTIONS
|
|
The
|
|
.Nm
|
|
driver has some private options,
|
|
which can be specified with an
|
|
.Dq option
|
|
statement in the kernel configuration file.
|
|
The following lists the private options.
|
|
The driver also accepts some other undocumented options,
|
|
all of whose names start with a fixed prefix
|
|
.Dv "FE_" .
|
|
Consult the source program for undocumented options.
|
|
.Bl -tag -width "FE_"
|
|
.It Dv "FE_DEBUG=" Ns Ar level
|
|
This option takes a numeric value
|
|
.Ar level
|
|
which controls the debugging level for the device and/or the driver.
|
|
Setting the
|
|
.Dv "FE_DEBUG"
|
|
option to a value which is not listed here
|
|
may cause undocumented behavior.
|
|
The default setting of this option is 1.
|
|
.Bl -bullet
|
|
.It
|
|
Setting
|
|
.Dv "FE_DEBUG=0"
|
|
makes most of debugging codes,
|
|
including sanity check,
|
|
be excluded from the object code of the driver.
|
|
It generates fastest and smallest object code.
|
|
Some emergency messages are logged even under this setting, though.
|
|
.It
|
|
Setting
|
|
.Dv "FE_DEBUG=1"
|
|
makes minimum debugging codes be included,
|
|
setting the amount of logged messages minimum.
|
|
Only fatal error messages are logged under this setting.
|
|
.It
|
|
Setting
|
|
.Dv "FE_DEBUG=2"
|
|
makes standard debugging codes be included,
|
|
setting the amount of logged messages middle.
|
|
Messages on lair events and/or questionable conditions
|
|
are logged under this setting.
|
|
.It
|
|
Setting
|
|
.Dv "FE_DEBUG=3"
|
|
makes all debugging codes be included,
|
|
and set the amount of legged messages maximum.
|
|
Redundant messages such as those reporting usual actions
|
|
or dumping register values
|
|
are logged under this setting.

.Sh FEATURES SPECIFIC TO HARDWARE MODELS
|
|
The
|
|
.Nm
|
|
driver has some features and limitations
|
|
which depend on adapter hardware models.
|
|
The following is a summary of such dependency.
|
|
.Ss Fujitsu FMV-180 series adapters
|
|
Both automatic IRQ detection and automatic I/O port address detection
|
|
is available with these adapters.
|
|
.Pp
|
|
Automatic I/O port address detection feature of
|
|
.Nm
|
|
works mostly fine for FMV-180 series.
|
|
It works even if there are two or more FMV-180s in a system.
|
|
However, some combination of other adapters may confuse the driver.
|
|
It is recommended to explicitly specify
|
|
.Ar port
|
|
when you experience some difficulties with hardware probe.
|
|
.Pp
|
|
Automatic IRQ detection feature of
|
|
.Nm
|
|
works reliably for FMV-180 series.
|
|
It is recommended to explicitly specify
|
|
.Ar irq
|
|
always for FMV-180.
|
|
The hardware setting of IRQ is read
|
|
from the configuration EEPROM on the adapter,
|
|
even when the kernel config file specifies an IRQ value.
|
|
The driver will generate a warning message,
|
|
if the IRQ setting specified in
|
|
.Pa /boot/device.hints
|
|
does not match one stored in EEPROM.
|
|
Then, it will use the value specified in the file.
|
|
(This behavior has been changed from the previous releases.)
|
|
.Ss Allied-Telesis AT1700 series and RE2000 series adapters
|
|
Automatic I/O port address detection
|
|
is available with Allied-Telesis AT1700 series and RE2000 series,
|
|
while it is less reliable than FMV-180 series.
|
|
Using the feature with Allied-Telesis adapters
|
|
is not recommended.
|
|
.Pp
|
|
Automatic IRQ detection is also available with some limitation.
|
|
The
|
|
.Nm
|
|
driver
|
|
tries to get IRQ setting from the configuration EEPROM on the board,
|
|
if
|
|
.Ar irq
|
|
is not specified in
|
|
.Pa /boot/device.hints .
|
|
Unfortunately,
|
|
AT1700 series and RE2000 series seems to have two types of models;
|
|
One type allows IRQ selection from 3/4/5/9,
|
|
while the other from 10/11/12/15.
|
|
Identification of the models are not well known.
|
|
Hence, automatic IRQ detection with Allied-Telesis adapters
|
|
may not be reliable.
|
|
Specify an exact IRQ number if any troubles are encountered.
|
|
.Pp
|
|
Differences between AT1700 series and RE2000 series
|
|
or minor models in those series are not recognized.
|
|
.Ss Fujitsu MBH10302 PC card
|
|
The
|
|
.Nm
|
|
driver supports Fujitsu MBH10302 and compatible PC cards.
|
|
It requires the PC card (PCMCIA) support package.

.Sh BUGS
|
|
Following are major known bugs:
|
|
.Pp
|
|
Statistics on the number of collisions maintained by the
|
|
.Nm
|
|
driver is not accurate;
|
|
the
|
|
.Fl i
|
|
option of
|
|
.Xr netstat 1
|
|
shows slightly less value than true number of collisions.
|
|
.Pp
|
|
More mbuf clusters are used than expected.
|
|
The packet receive routine has an intended violation
|
|
against the mbuf cluster allocation policy.
|
|
The unnecessarily allocated clusters are freed within short lifetime,
|
|
and it will not affect long term kernel memory usage.
|
|
.Pp
|
|
Although XNS and IPX supports are included in the driver,
|
|
they are never be tested and must have a lot of bugs.
