	* network/dec21140.c: Prevent name clashes by making 'ld_le32()' etc.
	static inlines.  Let dec21140 attach routine return an error rather
	than panic if no chip is detected (thus allowing for probing).
	* network/elnk.c: Let elnk bail out if autoneg never completes
	instead of looping forever.  Avoid divide by zero (crashed my PC).
	* network/if_fxp.c: Enable more fxp chip variants but warn that
	they are UNTESTED.
