A macro could help intelligibility here - maybe something like:

#define get_max_rate(r1, r2, r3, r4)					\
	(bw_40MHz ? (short_GI_40 ? r1 : r2) : (short_GI_20 ? r3 : r4))
and:
 		if (mcs->rx_mask[0] & BIT(7))
			max_rate = get_max_rate(1500, 1350, 722, 650);
		else if (mcs->rx_mask[0] & BIT(6))
			max_rate = get_max_rate(1350, 1215, 650, 585);
		else if (mcs->rx_mask[0] & BIT(5))
			max_rate = get_max_rate(1200, 1080, 578, 520);
		else if (mcs->rx_mask[0] & BIT(4))
			max_rate = get_max_rate(900, 810, 433, 390);
		else if (mcs->rx_mask[0] & BIT(3))
			max_rate = get_max_rate(600, 540, 289, 260);
		else if (mcs->rx_mask[0] & BIT(2))
			max_rate = get_max_rate(450, 405, 217, 195);
		else if (mcs->rx_mask[0] & BIT(1))
			max_rate = get_max_rate(300, 270, 144, 130);
		else if (mcs->rx_mask[0] & BIT(0))
			max_rate = get_max_rate(150, 135, 72, 65);

Hiding a parameter to a macro like that is bad coding practice, so don't
do that please!

Yes and no.

Adding the other 3 arguments to the macro doesn't help legibility.

Keeping the macro definition local to the place that it's used
can help avoid typos.

It's wrong, so just don't do it here!

It's not "wrong", you just don't like it.
