Tkip and michael crypto support for 802.11 devices

Usage

device wlan_tkip

Overview

The wlan_tkip module handles the TKIP and Michael cryptographic requirements of the WPA and 802.11i protocols. It does encapsulation and decapsulation of TKIP-encoded 802.11 frames and optionally calculates the TKIP cipher and Michael MIC. The wlan_tkip module is an 802.11 cryptographic plugin module for use by the wlan(4) module. This module is automatically loaded if a TKIP 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 TKIP and/or Michael calculations in hardware, the wlan_tkip module will do the work.
