40 module handles the AES-CCMP cryptographic requirements of the
41 WPA and 802.11i protocols.
42 It does encapsulation and decapsulation of CCMP-encoded 802.11 frames
43 and optionally calculates the AES-CCMP cipher.

54 Should the underlying network device not be capable of doing the AES-CCMP
55 calculations in hardware, the
