[PATCH 4/4] netdev: offload handshake when requested

[James Prestwood <prestwoj@gmail.com>]

[-- Attachment #1: Type: text/plain, Size: 1562 bytes --]

Set the PMK attribute if offloading the handshake is requested.
Since station relies on handshake events the key setting event
must be simulated in order to sync the PSK. As of now, no other
handshake events are required explicitly.
