Not all hardware are capable of generating their own RTS frames.
This patch will add support for creating the RTS frame in software,
when the driver requests this through the flag
IEEE80211_HW_SOFTWARE_RTS

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.

I sent a patchset that works with most (all?) hardware implementations,
as it uses library calls.

I also think that sending RTS in software is not going to work,
as the timing can not be guaranteed. And timing is why we do it in
the first place. If the HW is not capable of sending RTS frames, we
should not try to emulate them in SW, as it might make the situation
even worse by messing up the NAVs by wrong timing.
