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 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, otherwise
NULL is returned.

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