NAME
       il - Interlan NI1010 10 Mb/s Ethernet interface

SYNOPSIS
       device il0 at uba0 csr 164000 vector ilrint ilcint

DESCRIPTION
       The  _i_l interface provides access to a 10 Mb/s Ethernet network through
       an Interlan 1010 or 1010A controller.

       Each of the host’s network addresses is specified at boot time with  an
       SIOCSIFADDR  ioctl.   The  _i_l  interface employs the address resolution
       protocol described in _a_r_p(4P) to dynamically map between  Internet  and
       Ethernet addresses on the local network.

       The interface normally tries to use a ‘‘trailer’’ encapsulation to min‐
       imize copying data on input and output.  The use of trailers is negoti‐
       ated  with  ARP.   This negotiation may be disabled, on a per-interface
       basis, by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.

DIAGNOSTICS
       il%d: input error.  The hardware indicated an error in reading a packet
       off the cable or an illegally sized packet.

       il%d:  can’’t  handle  af%d.   The  interface  was handed a message with
       addresses formatted in an unsuitable address  family;  the  packet  was
       dropped.

       il%d:  setaddr  didn’’t work.  The interface was unable to reprogram its
       physical ethernet address.  This may happen with very early  models  of
       the  interface.   This facility is used only when the controller is not
       the first network interface configured for XNS.  The  oldest  interface
       tested (2.7.1.0.1.45) has never failed in this way.

       The  following  messages  indicate a probable hardware error performing
       the indicated operation  during  autoconfiguration  or  initialization.
       The status field in the control and status register (the low-order four
       bits) should indicate the nature of the failure.  See the hardware man‐
       ual for details.

       il%d: reset failed, csr=%b.

       il%d: status failed, csr=%b.

       il%d: hardware diag failed, csr=%b.

       il%d: verifying setaddr, csr=%b.

       il%d: stray xmit interrupt, csr=%b.

       il%d: can’’t initialize.
