NAME
fpa, fea - Device Drivers for DEC FDDI Controllers

SYNOPSIS
device fpa0
device fea0 at isa? net irq ? vector feaintr

FreeBSD only:
pseudo-device fddi

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.

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 different 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. Also the DEFEA can be configured with no device memory, this driver requires a mininum of 1K device memory be setup. The ECU (EISA Configuration 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.
