Aes-ccmp crypto support for 802.11 devices

Usage

device wlan_ccmp

Overview

The wlan_ccmp module handles the AES-CCMP cryptographic requirements of the WPA and 802.11i protocols. It does encapsulation and decapsulation of CCMP-encoded 802.11 frames and optionally calculates the AES-CCMP cipher. The wlan_ccmp module is an 802.11 cryptographic plugin module for use by the wlan(4) module. This module is automatically loaded if an AES-CCMP key is configured; typically by a WPA supplicant program such as wpa_supplicant, or a WPA authenticator program such as hostapd. Should the underlying network device not be capable of doing the AES-CCMP calculations in hardware, the wlan_ccmp module will do the work.
