Hi!
My/our setup:
I'm using my HP Elitebook 2540p with Intel 6200 abgn
pci id: 8086:4239 (rev 35)
Kernel from Fedora 14, compat-wireless-20101130, wpa_supplicant from GIT
with -D nl80211.
I try to connect to CISCO APs with 802.1x.
Everything works fine on 2.4GHz frequencies. But on 5GHz frequencies I
see the EAP Identity Request from the AP and I see the response in
wireshark.
But I don't see the response on an other laptop monitoring this channel
and the AP logs a timeout after a while for the EAP Request.
In the same moments I see

After the timeout wpa_supplicant restarts with an "EAPOL START" packet
and everything works cleanly.
I tried to shortcircuit the if in
net/mac80211/tx.c:1914ff
> if (!ieee80211_vif_is_mesh(&sdata->vif) &&
> unlikely(!is_multicast_ether_addr(hdr.addr1) &&
> !(sta_flags & WLAN_STA_AUTHORIZED) &&
> !(cpu_to_be16(ethertype) == sdata->control_port_protocol &&
> compare_ether_addr(sdata->vif.addr,
> skb->data + ETH_ALEN) == 0))) {
but that didn't help.
