Excelan 10 Mb/s Ethernet interface
ex0 at uba0 csr 164000 vector excdint
NOTE: This driver has not been ported from 4.4BSD yet.
The ex
interface provides access to a 10
Mb/s Ethernet network through an Excelan controller used as a link-layer
interface.
Each of the host's network addresses is specified at boot time
with an SIOCSIFADDR
ioctl(2). The
ex
interface employs the address resolution protocol
described in arp(4) to
dynamically map between Internet and Ethernet addresses on the local
network.
- ex%d: HW %c.%c, NX %c.%c, hardware address %s.
- This provides firmware revisions levels, and is expected during
autoconfiguration.
- ex%d: can't initialize.
- There was a failure in allocating UNIBUS resources for the device.
- ex%d: configuration failed; cc = %x.
- The hardware indicated an error when trying to initialize itself. The
error code returned is described at length in the device Reference
Manual.
- ex%d: receive error %b.
- The hardware indicated an error in reading a packet from the cable.
Specific Error bits are provided
- ex%d: transmit error %b.
- The hardware indicated an error in transmitting a packet to the cable or
an illegally sized packet. Specific Error bits are provided
- ex%d: can't handle af%d.
- The interface was handed a message with addresses formatted in an
unsuitable address family; the packet was dropped.
The ex
driver appeared in
4.3BSD.
