econet: remove ancient bug ridden protocol 

More spring cleaning!

The ancient Econet protocol should go. Most of the bug fixes in recent
years have been fixing security vulnerabilities. The hardware hasn't
been made since the 90s, it is only interesting as an archeological curiosity.

For the truly curious, or insomniac, go read up on it.

# Acorn Econet/AUN protocols

config ECONET

	tristate "Acorn Econet/AUN protocols (EXPERIMENTAL)"

	depends on EXPERIMENTAL && INET

	---help---

	  Econet is a fairly old and slow networking protocol mainly used by

	  Acorn computers to access file and print servers. It uses native

	  Econet network cards. AUN is an implementation of the higher level

	  parts of Econet that runs over ordinary Ethernet connections, on

	  top of the UDP packet protocol, which in turn runs on top of the

	  Internet protocol IP.



	  If you say Y here, you can choose with the next two options whether

	  to send Econet/AUN traffic over a UDP Ethernet connection or over

	  a native Econet network card.



	  To compile this driver as a module, choose M here: the module

	  will be called econet.



config ECONET_AUNUDP

	bool "AUN over UDP"

	depends on ECONET

	help

	  Say Y here if you want to send Econet/AUN traffic over a UDP

	  connection (UDP is a packet based protocol that runs on top of the

	  Internet protocol IP) using an ordinary Ethernet network card.



config ECONET_NATIVE

	bool "Native Econet"

	depends on ECONET

	help

	  Say Y here if you have a native Econet network card installed in

	  your computer.
