There is the AP the client initially connected to (A), the AP the client 
is currently connected to (B) and the AP the client aims to connect to 
Though, it might be that A=B, or A=C.
That indicates that A is the R0KH, B the current R1KH and C the new 

With FT-over-AIR, C will contact A.
With FT-over-DS, B will forward client packets to C, and C will contact 

Please double check the mappings in r0kh and r1kh.
