-.Sh NAME
-.Nm le
-.Nd AMD 7990 LANCE Ethernet interface driver
-.Sh SYNOPSIS
-.Cd "le* at obio0 addr ? level ?"
-.Cd "options LANCE_REVC_BUG"
-.Sh DESCRIPTION
-The 
-.Nm
-interface provides access to a 10 Mb/s
-.Tn Ethernet
-network via the
-.Tn AMD
-Am7990 and Am79C90 (CMOS, pin-compatible)
-.Tn LANCE
-(Local Area Network Controller - Ethernet) chip set.
-.Pp
-Each of the host's network addresses
-is specified at boot time with an
-.Dv SIOCSIFADDR
-.Xr ioctl 2 .
-The
-.Nm
-interface employs the Address Resolution Protocol (ARP) described in
-.Xr arp 4
-to dynamically map between Internet and
-.Tn Ethernet
-addresses on the local network.
-.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 is 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 bad this 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, with a list of
-what chip revisions were fabricated between which dates.
-.Pp
-Alas, this chip is so old that
-.Tn AMD
-has
-.Qq de-archived
-the information about it; pending a search elsewhere, we don't know how
-to identify the revision C chip from the date codes.
-.Sh DIAGNOSTICS
-.Bl -diag
-.It "le%d: overflow"
-More packets came in from the Ethernet than there was space in the
-receive buffers.
-Packets were missed.
-.It "le%d: receive buffer error"
-Ran out of buffer space, packet dropped.
-.It "le%d: lost carrier"
-The Ethernet carrier disappeared during an attempt to transmit.
-It will finish transmitting the current packet,
-but will not automatically retry transmission if there is a collision.
-.It "le%d: excessive collisions, tdr %d"
-Ethernet extremely busy or jammed,
-outbound packets dropped after 16 attempts to retransmit.
-.Pp
-.Sy TDR
-is
-.Qq Time Domain Reflectometry .
-The
-.Tn LANCE
-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"
-Packet didn't fit into a single receive buffer, packet dropped.
-.It "le%d: transmit buffer error"
-.Tn LANCE
-ran out of buffer before finishing the transmission of a packet.
-If this error occurrs, the driver software has a bug.
-.It "le%d: underflow"
-.Tn LANCE
-ran out of buffer before finishing the transmission of a packet.
-If this error occurrs, the driver software has a bug.
-.It "le%d: controller failed to initialize"
-Driver failed to start the AM7990
-.Tn LANCE .
-This is potentially a hardware failure.
-.It "le%d: memory error"
-.Tn 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
-.Tn LANCE
-receiver was turned off due to an error.
-.It "le%d: transmitter disabled"
-The
-.Tn LANCE
-transmitter was turned off due to an error.
