FEA(4) BSD Programmer's Manual FEA(4)NAME
fpa, fea - Device Drivers for DEC FDDI Controllers
SYNOPSIS
fpa0 at pci?
fea0 at eisa?
DESCRIPTION
The fpa and fea device driver provides support for the DEC DEFPA PCI FDDI
Controller and the DEC DEFEA EISA FDDI Controller, respectively. All
variants of either controller are supported including the DAS and SAS
configurations.
MEDIA SELECTION
Media options available are listed and manipulated via standard options
to the ifconfig(8) command.
DIAGNOSTICS
fea%d: error: desired IRQ of %d does not match device's actual IRQ (%d)
The device probe detected that the DEFEA board is configured for a dif-
ferent interrupt than the one specified in the kernel configuration file.
fea%d: error: memory not enabled! ECU reconfiguration required
The device probe found that no device memory had been configured on the
DEFEA. The DEFEA can be configured with no device memory, this driver
requires a minimum of 1K device memory be setup. The ECU (EISA Configu-
ration Utility) will need to be run to change the settings.
CAVEATS
Normally, the device driver will not enable the reception of SMT frames.
However if the IFF_LINK1 flag is set, the device driver will enable the
reception of SMT frames and pass them up to the Berkeley Packet Filter
for processing.
