EAP length is of 2 bytes, but currently the attribute type
used is NLA_U8. This causes the EAP packets with length
greater than 255 to print invalid length.
For roam current AP, the roamed AP info is printed.
Use NLA_U16 attribute for the EAP length and fill
correct event type for the current connected AP.
