>Description:
	The re, RealTek, ethernet driver tests for a board defect by
	sending and reading a packet in loopback mode.  This test false
	positives after rebooting from Windows XP.  After running Windows
	XP and then rebooting into FreeBSD, the re driver will report
	that the loopback test has failed.  An additional reboot will
	clear this problem.

	The card is in a 32-bit slot and thus should not have the
	bug the driver is trying to detect.  And in fact, the card works
	fine when it does get past the loopback test.
>How-To-Repeat:
	Boot Windows.  Restart and boot into FreeBSD.  System boot up
	will halt during loopback test.  Reboot again and it will
	succeed.
>Fix:
