I'm pretty sure this is from the TKIP part. There, the unicast key index
is indeed always 0. However, for WEP (and WEP only) this is not
regulated.

Yes, I was wrong here: Because Michael MIC only matters for TKIP it is
safe to assume that keyidx==0.
As for the ieee80211_rx_h_load_key, that doesn't exist in intel's
mac80211-9.0.4. I'll try wireless-dev again, but iwl4965 tends to hang
my computer a lot with other versions of mac80211.
