NAME¶
fe
—
Fujitsu MB86960A/MB86965A based Ethernet
adapters
SYNOPSIS¶
To compile this driver into the kernel, place the following line in your kernel configuration file:device fe
if_fe_load="YES"
hint.fe.0.at="isa"
hint.fe.0.port="0x300"
hint.fe.0.flags="0x0"
DESCRIPTION¶
Thefe
is a network device driver for
Ethernet adapters based on Fujitsu MB86960A, MB86965A, or other compatible
chips.
The driver provides automatic I/O port address configuration and automatic IRQ
configuration, when used with suitable adapter hardware.
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.
It currently works with Fujitsu FMV-180 series for ISA, Allied-Telesis AT1700
series and RE2000 series for ISA, and Fujitsu MBH10302 PC card.
Parameters¶
In the /boot/device.hints file, two parameters, port and irq, must be specified to reflect adapter hardware settings. Another parameter flags can be specified to provide additional configuration as an option. The port parameter specifies a base I/O port address of the adapter. It must match with the hardware setting of the adapter. The port may be left unspecified by removinghint.fe.0.port="..."
hint.fe.0.irq="..."
0x007F
- These flag bits are used to initialize DLCR6 register of MB86960A/MB86965A
chip, when the
0x0080
bit of the flags is set. See below for more about DLCR6 override feature. The0x007F
flag bits must be 0 unless the0x0080
bit is set, to maintain the compatibility with future versions of the driver. 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.

FEATURES SPECIFIC TO HARDWARE MODELS¶
Thefe
driver has some features and
limitations which depend on adapter hardware models. The following is a
summary of these dependencies.
Fujitsu FMV-180 series adapters¶
Both automatic IRQ detection and automatic I/O port address detection is available with these adapters. Automatic I/O port address detection feature offe
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 port when you experience
some difficulties with hardware probe.
Automatic IRQ detection feature of fe
works
reliably for FMV-180 series. It is recommended to explicitly specify
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
/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.)
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. Automatic IRQ detection is also available with some limitation. Thefe
driver tries to get IRQ setting from the
configuration EEPROM on the board, if irq is
not specified in /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.
Differences between AT1700 series and RE2000 series or minor models in those
series are not recognized.
Fujitsu MBH10302 PC card¶
Thefe
driver supports Fujitsu MBH10302 and
compatible PC cards. It requires the PC card (PCMCIA) support package.

BUGS¶
Following are major known bugs: Statistics on the number of collisions maintained by thefe
driver is not accurate; the
-i
option of
netstat(1) shows slightly less value than true
number of collisions.
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.
Although XNS and IPX support is included in the driver, it has never been tested
and it is expected to have a lot of bugs.July 16, 2005 | Debian |
