MIPS has since been removed from the tree and emulators and virtual machines offer many other, more suitable devices.

"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. -.El -.Sh SEE ALSO -.Xr

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. diff --git a/sys/amd64/conf/GENERIC b/sys/amd64/conf/GENERIC index c390ff7596b6..0868cdfc95e7 100644 ---
