Ah, I do not know that.  So clk_enet_ref_table is actually buggy?

Yes, that's much better for reading.  But to be consistent with
clk_enet_ref_table, please also put a comma after .div.

Per Reference Manual, we should have one more entry below?

	{ .val = 2, .div = 1, }

Yea, that's much easier for users to map code and document.
