802.11 WEP encryption
struct mbuf *
ifnet *ifp, struct mbuf
These functions provide software encryption support for 802.11 device drivers.
function initializes crypto support for the interface
ifp, and sets the initialization vector (IV) for WEP
encryption to a random number derived from a secure PRNG.
function frees data structures associated with crypto support for the
function runs the appropriate WEP encryption algorithm over the 802.11
encapsulated frame held in the mbuf chain m0, for
transmission or reception on the interface ifp. The
txflag argument specifies whether the frame is being
received or transmitted. A value of 0 indicates that the frame is being
received and should therefore be decrypted; a non-zero value indicates that
the frame is being transmitted and should be encrypted.
ieee80211_wep_crypt() function stores
its IV in the interface's embedded struct ieee80211com
ieee80211 series of functions first
appeared in NetBSD 1.5, and were later ported to
FreeBSD 4.6 and OpenBSD
