Name
       ne - Second Generation Ethernet Chip Interface

Syntax
       device ne0 at ibus? vector neintr

Description
       The interface provides access to a 10 Mb/s Ethernet network through the Digital's Second Generation Ethernet Chip (SGEC) based controller.

       The  host's  Internet  address  is specified at boot time with an SIOCSIFADDR ioctl.  The interface employs the address resolution protocol
       described in to map dynamically between Internet and Ethernet addresses on the local network.

       The driver normally tries to use a trailer encapsulation to minimize copying data on input and output.  This can be disabled for an  inter-
       face by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.  Trailers are only used for packets destined for Internet hosts.

       The SIOCSPHYSADDR ioctl can be used to change the physical address of the adapter and the SIOCRPHYSADDR ioctl can be used to read its phys-
       ical address.

       The SIOCADDMULTI and SIOCDELMULTI ioctls can be used to add or delete multicast addresses.   The  recognizes  a	maximum  of  16  multicast
       addresses.

       The SIOCRDCTRS and SIOCRDZCTRS ioctls can be used to read or read and clear the Ethernet driver counters.  The argument to these two ioctls
       is a pointer to a counter structure, found in

       The SIOCENABLBACK and SIOCDISABLBACK ioctls can be used to enable and disable the interface loopback mode respectively.

Diagnostics
       The diagnostic error messages contain relevant information provided by the driver. For example,

       ne%d: self test failed <reason lists>
       Adapter did not pass the power-up self-test during autoconfiguration time.

       ne%d: write CSR0 failed
       The driver was unable to set the initial value for the adapter.

       ne%d: couldn't allocate ......
       The driver was unable to allocate memory for the internal data structures.  ne%d: can't handle af%d
       The interface was handed a message with addresses formated in an unsuitable address family, and the packet was dropped.

       ne%d: memory error (MERR)
       A host memory problem or a memory parity error has occurred.

       ne%d: SIOCADDMULTI fail, multicast list full
       Too many multicast requests have been made.
