Its true, wpa_supplicant and the unicast frames all have keyidx==3. I
added these printk's:
=============
if (rx->fc & IEEE80211_FCTL_PROTECTED) {
if (rx->skb->pkt_type == PACKET_HOST)
printk(KERN_DEBUG "%s: RX WEP unicast frame from "
MAC_FMT " with keyidx %d\n",
rx->dev->name, MAC_ARG(hdr->addr2),
ieee80211_wep_get_keyidx(rx->skb) );
if (rx->skb->pkt_type == PACKET_HOST &&
rx->sta && rx->sta->key) {
rx->key = rx->sta->key;
printk(KERN_DEBUG "Using STA key\n");
=============
Then I get a debug log that contains a lot of
