For example with a ping I can see at the reception that all the ICMP packets have 16 Bytes less, but also the ARP packets. They are well decrypted by the AP though. At the second rekey, the ptk handshake doesn't work because the EAPOL packets are truncated, hostapd says 'frame too short for this IEEE 802.1X packets' and disconnects the STA. With a 3rd radio I can tell that the packets are truncated also in the air so it must be a STA problem. With the htt_dump (on the STA) debug option of ath10k I can tell that the packets are not altered here, the frames are ok The problem still exists with latest compat-wireless (2015-12-03) and latest QCA988X firmware : firmware-5.bin_10.2.4.70.15-2 I am using two compex cards (WLE900VX). Thanks in advance for the help. _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
