	i (and momo@iij.ad.jp) have confirmed that we really need this patch,
	because of the following story:
	- ether_ioctl() returns ENETRESET to inform of filter change to
	  driver
	- an_ioctl() passes ENETRESET to upper layers
	- upper layer (including sys/netinet6/in6.c) considers ENETRESET as
	  a fatal error and will go trouble.

	my understanding is that ENETRESET is used only between ether_ioctl
	and xx_ioctl, and has to be hiddent from upper layers.

	1.5 code is okay.
