In current implementaion, upon an EAP method failure, followed
by an EAP failure, the EAP Status is propagated up in wpa_supplicant
with a general failure parameter string "failure". This parameter is
used for a notification on the dbus.
This patch reports the EAP method failure error code in a separate
callback. We want this to have visibility into the error code and act
accordingly.
The solution in this patch is generic to all EAP methods, and can be
used by any method that need to pass its error code. However, this
patch only implements the reporting for EAP-SIM, EAP-AKA, and EAP-AKA'
methods.

Subject: [PATCH 1/2] Propagate the EAP method error code
In current implementaion, upon an EAP method failure, followed
by an EAP failure, the EAP Status is propagated up in wpa_supplicant
with a general failure parameter string "failure". This parameter is
used for a notification on the dbus.
This commit reports the EAP method failure error code in a separate
callback.
The solution in this commit is generic to all EAP methods, and can be
used by any method that need to pass its error code. However, this
commit only implements the reporting for EAP-SIM and EAP-AKA methods.
