[PATCH 2/6] brcmfmac: send port authorized event for 802.1X 4-way handshake offload

[Chi-Hsien Lin <Chi-Hsien.Lin@cypress.com>]

From: Chung-Hsien Hsu <stanley.hsu@cypress.com>

With 4-way handshake offload for 802.1X authentication, a port
authorized event should be sent to user space after the completion of
4-way handshake. It is used to indicate that a connection is authorized
and 802.1X authentication is no longer required.
