#938: IP packet are sent uncrypted while roaming

Priority: major | Milestone:
Component: madwifi: driver | Version: v0.9.2

-------------------------------+--------------------------------------------
In a private network the moving clients using static IP addresses
are sending a constant flow of UDP packet through ath0.
When the contact is lost from the previous AP, data stopped to be
xmited because the device queue is stopped by the driver.
When the client is associated with the new AP, the device queue is
enable and the queued IP packets, as well as new ones, start to be
sent unencrypted before authentication takes place.
EAP packets are sent by wpa_supplicant through a raw socket using
LLC2 ethernet type 0x888E. They go through the device xmit queue
like any IP packets.
When the EAP/LEAP EAPOL key exchanges are done then the IP packets
get encrypted again.
There is also a side effect which is that the IP packets slow down
the authentication process by using the bandwith.
