+The value
+.B net
+specifies ``netconsole'' which sends console messages as UDP packets over the network.
+It bypasses the IP stack and writes Ethernet packets directly to the NIC.
+In this case
+.I params
+is mandatory and takes the form
+.IP

+.LP
+\fISrcip\fR, \fIsrcport\fR (default 6665), \fIdstip\fR and \fIdstport\fR (default 6666) specify the source IP address, source port, destination IP address and destination port, respectively.
+\fIDevno\fR (default 0) specifies which NIC to use, a value of \fIn\fR corresponds to NIC at \fL#l\fIn\fR (see
+.IR ether (3)).
+\fIDstmac\fR specifies the destination MAC address; broadcast packets are sent if it is unspecified.
+Note that it is possible, but not recommended, to send packets to a host outside the local network by specifying the MAC address of the gateway as \fIdstmac\fR.
+Example lines are
