What do you propose? Do we need something like

int vlan_adjust_mtu (int mtu)
{
#ifdef CONFIG_VLANN_8021Q
	return (mtu - VLAN_HLEN);
#else
	return (mtu);
#endif
}

and

int foobar_change_mtu (struct net_device *dev, int mtu)
{
	mtu = vlan_adjust_mtu (mtu);
	/* check hardware limits. */
	...
	dev->mtu = mtu;
	return (0);
}

? Ben, this would also keep you happy, right?

I was thinking the check could be made run-time, but in reality, this is
a very minor detail.  It may be better to just hard-code it like you
had it originally.  I don't like the patch above, I'd rather see the
#ifdef when checking for the maximum hardware limit, if anywhere.

Thanks,
Ben
