Ideally, it'd look something like:
	  
		/* Set the driver state */
		/* Do we want the prism2 header? */
		if (msg->prismheader.status == P80211ENUM_msgitem_status_data_ok &&
		    msg->prismheader.data == P80211ENUM_truth_true) {
			hw->sniffhdr = 0;
			wlandev->netdev->type = ARPHRD_IEEE80211_PRISM;
		} else if (msg->wlanheader.status == P80211ENUM_msgitem_status_data_ok &&
			   msg->wlanheader.data == P80211ENUM_truth_true) {
			hw->sniffhdr = 1;
			wlandev->netdev->type = ARPHRD_IEEE80211_PRISM;
		} else {
			wlandev->netdev->type = ARPHRD_IEEE80211;
		}

with the unnecessary parentheses removed,
the logical continuations at the end-of-line,
and the else if on a single line.
