56 These functions handle the encapsulation and transmission of 802.11 frames
57 within the software 802.11 stack.
61 function encapsulates an outbound data frame contained within the
68 is a reference to the destination node.
70 If the function is successful, the mbuf chain is updated with the
71 802.11 frame header prepended, and a pointer to the head of the chain
79 The caller is responsible for freeing the node reference if
84 The convention is that

92 utility function is used to add the rate set element

108 A pointer to the location in the buffer after the addition of the rate set
