NAME

     ieee80211_crypto_attach, ieee80211_crypto_detach, ieee80211_crypto_encap
     -- 802.11 WEP encryption functions


SYNOPSIS

     void
     ieee80211_crypto_attach(struct ieee80211com *ic);

     void
     ieee80211_crypto_detach(struct ieee80211com *ic);

     struct ieee80211_key *
     ieee80211_crypto_encap(struct ieee80211com *ic,
         struct ieee80211_node *ni, struct mbuf *m0);


DESCRIPTION

     These functions provide encryption support for 802.11 device drivers.

     The ieee80211_crypto_attach() function initializes crypto support for the
     interface ic.  The default is null crypto.

     The ieee80211_crypto_detach() function frees data structures associated
     with crypto support for the interface ic.

     The two above functions are automatically called by the interface attach
     and detach routines, respectively.

     The ieee80211_crypto_encap() function encapsulates the packet supplied in
     mbuf m0, with the crypto headers given the for node ni.  Software encryp-
     tion is possibly performed.  In case of no specified key for ni or multi-
     cast traffic, the default key for the interface ic is used for encapsula-
     tion.  The key is returned in the case of successful encapsulation, oth-
     erwise NULL is returned.

HISTORY

     The ieee80211 series of functions first appeared in NetBSD 1.5, and were
     later ported to FreeBSD 4.6.
