NAME

6       il - Interlan NI1010 10 Mb/s Ethernet interface
7

SYNOPSIS

9       /sys/conf/SYSTEM:
10            NIL  il_controllers # Interlan Ethernet
11

DESCRIPTION

13       The  il interface provides access to a 10 Mb/s Ethernet network through
14       an Interlan 1010 or 1010A controller.
15
16       Each of the host's network addresses is specified at boot time with  an
17       SIOCSIFADDR  ioctl.   The  il  interface employs the address resolution
18       protocol described in arp(4P) to dynamically map between  Internet  and
19       Ethernet addresses on the local network.
20
21       The interface normally tries to use a ``trailer'' encapsulation to min‐
22       imize copying data on input and output.  The use of trailers is negoti‐
23       ated  with  ARP.   This negotiation may be disabled, on a per-interface
24       basis, by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.

DIAGNOSTICS

27       il%d: input error.  The hardware indicated an error in reading a packet
28       off the cable or an illegally sized packet.
29
30       il%d:  can't  handle  af%d.   The  interface  was handed a message with
31       addresses formatted in an unsuitable address  family;  the  packet  was
32       dropped.
33
34       il%d:  setaddr  didn't work.  The interface was unable to reprogram its
35       physical ethernet address.  This may happen with very early  models  of
36       the  interface.   This facility is used only when the controller is not
37       the first network interface configured for XNS.  The  oldest  interface
38       tested (2.7.1.0.1.45) has never failed in this way.
39
40       The  following  messages  indicate a probable hardware error performing
41       the indicated operation  during  autoconfiguration  or  initialization.
42       The status field in the control and status register (the low-order four
43       bits) should indicate the nature of the failure.  See the hardware man‐
44       ual for details.
45
46       il%d: reset failed, csr=%b.
47
48       il%d: status failed, csr=%b.
49
50       il%d: hardware diag failed, csr=%b.
51
52       il%d: verifying setaddr, csr=%b.
53
54       il%d: stray xmit interrupt, csr=%b.
55
56       il%d: can't initialize.
