sys: Retire le(4)

We retired most obsolete 10 and 10/100 Ethernet NIC drivers in 2019 --
see commits following ebcf740a32ae ("FCP-101: remove obsolete 10 and
10/100 Ethernet drivers.).

le(4) was retained with with the note "Emulated by QEMU, alternatives
don't yet work for mips64."  MIPS has since been removed from the tree
and emulators and virtual machines offer many other, more suitable
devices.

-.Sh NAME
-.Nm le
-.Nd "AMD Am7900 LANCE and Am79C9xx ILACC/PCnet Ethernet interface driver"
-.Sh SYNOPSIS
-To compile this driver into the kernel,
-place the following line in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device le"
-.Ed
-.Pp
-Alternatively, to load the driver as a
-module at boot time, place the following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-if_le_load="YES"
-.Ed
-.Pp
-For ISA non-PnP adapters, the port address as well as the IRQ and the DRQ
-numbers have to be specified in
-.Pa /boot/device.hints :
-.Cd hint.le.0.at="isa"
-.Cd hint.le.0.port="0x280"
-.Cd hint.le.0.irq="10"
-.Cd hint.le.0.drq="0"
-.Sh DEPRECATION NOTICE
-The
-.Nm
-driver may not be present in
-.Fx 16.0
-and later.
-.Sh DESCRIPTION
-The
-.Nm
-driver provides support for Ethernet adapters based on the
-.Tn AMD Am7990
-and
-.Tn Am79C90
-.Pq CMOS, pin-compatible
-Local Area Network Controller for Ethernet
-.Pq Tn LANCE
-chips.
-.Pp
-The
-.Nm
-driver also supports Ethernet adapters based on the
-.Tn AMD Am79C900
-Integrated Local Area Communications Controller
-.Pq Tn ILACC
-as well as the
-.Tn Am79C9xx PCnet
-family of chips, which are single-chip implementations of a
-.Tn LANCE
-chip and a DMA engine.
-The
-.Nm
-driver treats all of these
-.Tn PCI
-bus Ethernet chips as an
-.Tn AMD Am79C970 PCnet-PCI
-and does not support the additional features like the MII bus and burst mode of
-.Tn AMD Am79C971 PCnet-FAST
-and greater chips.
-.Pp
-Generally, the
-.Nm
-driver aims at supporting as many different chips on as many different
-platforms as possible,
-partially at the cost of the best performance with some of these.
-.Pp
-The
-.Nm
-driver supports reception and transmission of extended frames for
-.Xr vlan 4 .
-Selective reception of multicast Ethernet frames is provided by a 64-bit mask;
-multicast destination addresses are hashed to a bit entry using the Ethernet
-CRC function.
-.Sh HARDWARE
-.Ss ISA
-The
-.Nm
-driver supports
-.Tn ISA
-bus Ethernet adapters which are based on the following chips:
-.Pp

-driver supports the selection of the following media types via
-.Xr ifconfig 8
-with
-.Tn PCI
-bus Ethernet adapters:
-.Bl -tag -width ".Cm 10base5/AUI"
-.It Cm autoselect
-Enable autoselection of the media type.
-.It Cm 10baseT/UTP
-Select UTP media.
-.It Cm 10base5/AUI

-.El
-.Pp
-The following media option is supported with these media types:
-.Bl -tag -width ".Cm full-duplex"
-.It Cm full-duplex
-Select full duplex operation.
-.El
-.Pp
-Note that the
-.Nm
-driver does not support selecting 100Mbps (Fast Ethernet) media types.
-.Sh DIAGNOSTICS
-.Bl -diag
-.It "le%d: overflow"
-More packets came in from the Ethernet than there was space in the
-.Tn LANCE
-receive buffers.
-Packets were missed.
-.It "le%d: receive buffer error"
-The
-.Tn LANCE
-ran out of buffer space, packet dropped.
-.It "le%d: lost carrier"
-The Ethernet carrier disappeared during an attempt to transmit.
-The
-.Tn LANCE
-will finish transmitting the current packet,
-but will not automatically retry transmission if there is a collision.
-.It "le%d: excessive collisions, tdr %d"
-The Ethernet was extremely busy or jammed,
-outbound packets were dropped after 16 attempts to retransmit.
-.Pp
-TDR
-is the abbreviation of
-.Qq Time Domain Reflectometry .
-The optionally reported TDR value is an internal counter of the interval
-between the start of a transmission and the occurrence of a collision.
-This value can be used to determine the distance from the Ethernet tap to
-the point on the Ethernet cable that is shorted or open (unterminated).
-.It "le%d: dropping chained buffer"
-A packet did not fit into a single receive buffer and was dropped.
-Since the
-.Nm
-driver allocates buffers large enough to receive maximum sized Ethernet
-packets, this means some other station on the LAN transmitted a packet
-larger than allowed by the Ethernet standard.
-.It "le%d: transmit buffer error"
-The
-.Tn LANCE
-ran out of buffer space before finishing the transmission of a packet.
-If this error occurs, the driver software has a bug.
-.It "le%d: underflow"
-The
-.Tn LANCE
-ran out of buffer space before finishing the transmission of a packet.
-If this error occurs, the driver software has a bug.
-.It "le%d: controller failed to initialize"
-Driver failed to start the
-.Tn LANCE .
-This is potentially a hardware failure.
-.It "le%d: memory error"
-RAM failed to respond within the timeout when the
-.Tn LANCE
-wanted to read or write it.
-This is potentially a hardware failure.
-.It "le%d: receiver disabled"
-The receiver of the
-.Tn LANCE
-was turned off due to an error.
-.It "le%d: transmitter disabled"
-The transmitter of the
-.Tn LANCE
-was turned off due to an error.

-.Sh HISTORY
-The
-.Nm
-driver was ported from
-.Nx
-and first appeared in
-.Fx 6.1 .
-The
-.Nx
-version in turn was derived from the
-.Nm
-driver which first appeared in
-.Bx 4.4 .
-.Sh AUTHORS
-The
-.Nm
-driver was ported by
-.An Marius Strobl Aq Mt marius@FreeBSD.org .
-.\" .Sh BUGS
-.\" The Am7990 Revision C chips have a bug which causes garbage to be inserted
-.\" in front of the received packet occasionally.
-.\" The work-around is to ignore packets with an invalid destination address
-.\" (garbage will usually not match), by double-checking the destination
-.\" address of every packet in the driver.
-.\" This work-around can be enabled with the
-.\" .Dv LANCE_REVC_BUG
-.\" kernel option.
-.\" .Pp
-.\" When
-.\" .Dv LANCE_REVC_BUG
-.\" is enabled, the
-.\" .Nm
-.\" driver executes one or two calls to an inline Ethernet address comparison
-.\" function for every received packet.
-.\" On the
-.\" .Tn MC68000
-.\" it is exactly eight instructions of 16 bits each.
-.\" There is one comparison for each unicast packet, and two comparisons for
-.\" each broadcast packet.
-.\" .Pp
-.\" In summary, the cost of the LANCE_REVC_BUG option is:
-.\" .Bl -enum -compact
-.\" .It
-.\" loss of multicast support, and
-.\" .It
-.\" eight extra
-.\" .Tn CPU
-.\" instructions per received packet, sometimes sixteen, depending on both the
-.\" processor, and the type of packet.
-.\" .El
-.\" .Pp
-.\" All sun3 systems are presumed to have this bad revision of the Am7990,
-.\" until proven otherwise.
-.\" Alas, the only way to prove what revision of the chip is in a particular
-.\" system is inspection of the date code on the chip package,
-.\" to compare against a list of what chip revisions were fabricated between
-.\" which dates.
-.\" .Pp
-.\" Alas, the Am7990 chip is so old that
-.\" .Tn AMD
-.\" has
-.\" .Qq de-archived
-.\" the production information about it; pending a search elsewhere, we do not
-.\" know how to identify the revision C chip from the date codes.
