[PATCH] libertas: Make WPA work through supplicant handshake
Fix WPA so it works up through the supplicant 4-Way handshake process. Doesn't successfully pass traffic yet; may be problems installing the GTK to the firmware. - RSN needs to be enabled before the association command is sent - Use keys from the association request not the adapter structure - cmd_act_mac_strict_protection_enable != IW_AUTH_DROP_UNENCRYPTED - Fix network filtering logic in is_network_compatible() WPA helpers Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.
