[PATCH 03/12] handshake: add flags/key_index for extended key IDs

[James Prestwood <prestwoj at gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 1131 bytes --]

ext_key_id_capable indicates the handshake has set the capability bit
in the RSN info. This will only be set if the AP also has the capability
set.

use_ext_key_id indicates if extended key ID procedure should be used.
This is required because an AP may not send the KDE (even with capabilities
set) meaning we fall back to the legacy zero key index.

ptk_index is the key index the AP chose for a given rekey.
