dgrs: remove from build, config, and maintainer list 

Stop building and configuring driver for Digi RightSwitch, which was
never actually sold to anyone, and remove it from MAINTAINERS.

In response to an investigation into the firmware of the "Digi Rightswitch"
driver, Andres Salomon discovered:

Since the product never reached market, clearly nobody is using this orphaned
driver.

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.

For information on purchasing a RightSwitch SE-4 or SE-6
board, please contact Digi's sales department at 1-612-912-3444
or 1-800-DIGIBRD. Outside the U.S., please check our Web page at:
http://www.dgii.com
for sales offices worldwide. Tech support is also available through
the channels listed on the Web site, although as long as I am
employed on networking products at Digi I will be happy to provide
any bug fixes that may be needed.

* The bios low-memory structure
*
* Some of the variables in here can be used to set parameters that
* are stored in NVRAM and will retain their old values the next time
* the card is brought up. To use the values stored in NVRAM, the
* parameter should be set to "all ones". This tells the firmware to
* use the NVRAM value or a suitable default. The value that is used
* will be stored back into this structure by the firmware. If the
* value of the variable is not "all ones", then that value will be
* used and will be stored into NVRAM if it isn't already there.
* The variables this applies to are the following:
* Variable Set to: Gets default of:
* bc_hashexpire -1 300 (5 minutes)
* bc_spantree -1 1 (spanning tree on)
* bc_ipaddr FF:FF:FF:FF 0 (no SNMP IP address)
* bc_ipxnet FF:FF:FF:FF 0 (no SNMP IPX net)
* bc_iptrap FF:FF:FF:FF 0 (no SNMP IP trap address)
*
* Some variables MUST have their value set after the firmware
* is loaded onto the board, but before the processor is released.
* These are:
* bc_host 0 means no host "port", run as standalone switch.
* 1 means run as a switch, with a host port. (normal)
* 2 means run as multiple NICs, not as a switch.
* -1 means run in diagnostics mode.
* bc_nowait
* bc_hostarea_len
* bc_filter_len
