I assert xoff_gen for 4 Rx clock cycles. I don't remember how I came up with that but I know it works. I also know that if you keep it high, or set the corresponding register bit, the MAC will send constant pause frames (my software guy was at one point incorrectly setting the register bit and leaving it set).
