ln(7)ln(7)Nameln - Lance Ethernet interface
device ln0 at ibus? vector lnintr
The interface provides access to a 10 Mb/s Ethernet network through the
The host's Internet address is specified at boot time with an SIOCSI‐
FADDR ioctl. The interface employs the address resolution protocol
described in to map dynamically between Internet and Ethernet addresses
on the local network.
The interface 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 Lance. The SIOCRPHYSADDR ioctl can be used to read the physical
address of the Lance.
The SIOCADDMULTI and SIOCDELMULTI ioctls can be used to add or delete
multicast addresses. The Lance recognizes a maximum of 12 multicast
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.
The diagnostic error messages contain relevant information provided by
ln%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.
ln%d: memory error (MERR)
A memory parity error has occurred.
ln%d: lnalloc: cannot alloc memory ...
The driver was unable to allocate memory for internal data structures.
ln%d: initialization error
The driver was unable to initialize the network interface.
ln%d: SIOCADDMULTI fail, multicast list full
Too many multicast requests have been made.
