It seems this is not the ideal solution. Most of drivers needing
software RTS would need to remember the RTS frame somewhere (as they
need to pass it together with the actual frame).

A better solution would be either to pass a pointer to RTS frame data
in tx_control or to create a function returning RTS frame.
