53 These functions handle the encapsulation and transmission of 802.11 frames
54 within the software 802.11 stack.
58 function encapsulates an outbound data frame contained within the
65 is a reference to the destination node.
67 If the function is successful, the mbuf chain is updated with the
68 802.11 frame header prepended, and a pointer to the head of the chain
76 The caller is responsible for freeing the node reference if
81 The convention is that

88 .Fn ieee80211_add_rates
89 utility function is used to add the rate set element
93 A pointer to the location in the buffer after the addition of the rate set
95 It is typically used when constructing management frames from within the
96 software 802.11 stack.
100 .Fn ieee80211_add_xrates
101 utility function is used to add the extended rate set element
105 A pointer to the location in the buffer after the addition of the rate set
107 It is typically used when constructing management frames from within the
108 software 802.11 stack in 802.11g mode.
112 .Fn ieee80211_send_mgmt
113 function transmits a management frame on the interface
115 to the destination node
122 specifies either a sequence number for authentication operations,
