RE: [PATCH net-next] bridge: Fix incorrect judgment of promisc

From: Toshiaki Makita

A quick truth table:
	auto_cnt	auto_port	set/clear
		0		0	clear
		0		1	clear
		1		0	set
		1		1	clear
		2+		0/1	clear

The last line should be set.

I've clearly not drunk enough coffee today...

I suspect the 0-1 line is impossible.
Since the check is probably for 'any other ports in 'auto' mode'.
So:
	if (auto_cnt - auto_port > 0)
(which is much the same as the original) is a good descriptive test.
