This is the function body:

	/* Switchdev offloading can be configured on: */

	if (dev == dp->slave)
		/* DSA ports directly connected to a bridge. */
		return true;

	if (dp->lag && dev == dp->lag->dev)
		/* DSA ports connected to a bridge via a LAG */
		return true;

	return false;

What more is there to explain? Is it the style?  Do you prefer initial
block comments over explaining the individual statements? Is the lanuage
not up to standard?

I am sorry for the tone, I am aware of it. It is just that I really want
to contributem but I am starting to feel like a tty-over-email-proxy to
my emacs session - and an extremely unreliable one at that.
