[vincent guffens <v.guffens@imperial.ac.uk>]

And here comes the last part, this test driver detects the ne2000 card
in qemu.



2006-05-16  Vincent Guffens  <vinsz@fsfe.org>

	* drivers/net/: New directory.

	* conf/i386-pc.rmk (pkgdata_MODULES): Added test_driver.mod
	to the list of modules.
	(test_driver_mod_SOURCES): Added.
	(test_driver_mod_CFLAGS): Likewise.
	(test_driver_mod_LDFLAGS): Likewise.

	* driver/net/test_driver.c: New file.
