54 These functions handle the encapsulation and transmission of 802.11 frames
55 within the software 802.11 stack.
59 function encapsulates an outbound data frame contained within the
66 is a reference to the destination node.
68 If the function is successful, the mbuf chain is updated with the
69 802.11 frame header prepended, and a pointer to the head of the chain
77 The caller is responsible for freeing the node reference if
82 The convention is that

90 utility function is used to add the rate set element
94 A pointer to the location in the buffer after the addition of the rate set

102 utility function is used to add the extended rate set element
106 A pointer to the location in the buffer after the addition of the rate set

109 software 802.11 stack in 802.11g mode.

114 function transmits a management frame on the interface
