ix -- Interlan Np100 10 Mb/s Ethernet interface
np0 at uba0 csr 166000 vector npintr
NOTE: This driver has not been ported from 4.4BSD yet. The ix interface provides access to a 10 Mb/s Ethernet network through an Interlan Np100 controller used as a link-layer interface. This interface is unusual in that it requires loading firmware into the controller before it may be used as a network interface. This is accom- plished by opening a character special device, and writing data to it. A program to load the image is provided in /usr/src/new/np100. The sequence of commands would be: # ./npload np.image [/dev/np<board #> if other than np00] # sleep 10 # ifconfig ix0 ... Each of the host's network addresses is specified at boot time with an SIOCSIFADDR ioctl(2). The ix interface employs the address resolution protocol described in arp(4) to dynamically map between Internet and Eth- ernet addresses on the local network.
ix%d: Req failed, cmd %x, stat %x, ust error %x,%x. The firmware in the controller refused to honor a request from UNIX in initializing packet level communications. The board may need to be reset and reloaded. Or, you may not have allowed enough time between loading the board and issu- ing the request to begin UNIX network operation. ix%d: can't initialize. The interface was unable to obtain UNIBUS resources required for operation. ix%d: failed to reinitialize DLA module. The interface got sick after attempting to reprogram its physical Ethernet address. Try reloading the firmware. The attempt is made only when this interfaces is not the first one configured for XNS. ix%d: can't handle af%d. The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped. ix%d: stray xmit interrupt, npreq=%x. This may happen if the board is reloaded while network processes are still running. ixrint: cqe error %x, %x, %x. This will result if an ifconfig(8) request is made at an inopportune time, such as not allowing enough time after loading the firmware. After 100 such errors are logged, the UNIX network driver will shut itself down, saying: ixrint: shutting down unix dla. The recourse is to reload the firmware and allow more time.
