Does version3 firmware have a different bitlayout for the status?

It seems so. I found this because I was not getting any acks back to net/mac80211/rc80211_pid_algo.c. I then reviewed the V3 specs, found that bit 0, not bit 1, contained the ack. Test prints confirmed that result. With this patch, both my BCM4306/2 and BCM4303 reach the maximum rate. With the current code, 54 Mb/s is not as fast as 36 Mb/s, but at least the algorithm is working.
