* b2b\_mw\_share - If the peer ntb is to be accessed via a memory window, and if
the memory window is large enough, still allow the client to use the
second half of the memory window for address translation to the peer.
* snb\_b2b\_usd\_bar2\_addr64 - If using B2B topology on Xeon hardware, use this
64 bit address on the bus between the NTB devices for the window at
BAR2, on the upstream side of the link.
