NetBSD 6.1.5 - man page for ieee80211_crypto (netbsd section 9)

IEEE80211_CRYPTO(9)		  BSD Kernel Developer's Manual 	      IEEE80211_CRYPTO(9)

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 rou-
     tines, respectively.

     The ieee80211_crypto_encap() function encapsulates the packet supplied in mbuf m0, with the
     crypto headers given the for node ni.  Software encryption is possibly performed.	In case
     of no specified key for ni or multicast traffic, the default key for the interface ic is
     used for encapsulation.  The key is returned in the case of successful encapsulation, other-
     wise NULL is returned.

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