+ The Digi International RightSwitch SE-X (dgrs) Device Driver
+
+This is a Linux driver for the Digi International RightSwitch SE-X
+EISA and PCI boards. These are 4 (EISA) or 6 (PCI) port Ethernet
+switches and a NIC combined into a single board. This driver can
+be compiled into the kernel statically or as a loadable module.
+
+There is also a companion management tool, called "xrightswitch".
+The management tool lets you watch the performance graphically,
+as well as set the SNMP agent IP and IPX addresses, IEEE Spanning
+Tree, and Aging time. These can also be set from the command line
+when the driver is loaded. The driver command line options are:
+
+ debug=NNN Debug printing level
+ dma=0/1 Disable/Enable DMA on PCI card
+ spantree=0/1 Disable/Enable IEEE spanning tree
+ hashexpire=NNN Change address aging time (default 300 seconds)
+ ipaddr=A,B,C,D Set SNMP agent IP address i.e. 199,86,8,221
+ iptrap=A,B,C,D Set SNMP agent IP trap address i.e. 199,86,8,221
+ ipxnet=NNN Set SNMP agent IPX network number
+ nicmode=0/1 Disable/Enable multiple NIC mode
+
+There is also a tool for setting up input and output packet filters
+on each port, called "dgrsfilt".
+
+Both the management tool and the filtering tool are available
+separately from the following FTP site:
+
+ ftp://ftp.dgii.com/drivers/rightswitch/linux/
+
+When nicmode=1, the board and driver operate as 4 or 6 individual
+NIC ports (eth0...eth5) instead of as a switch. All switching
+functions are disabled. In the future, the board firmware may include
+a routing cache when in this mode.
