Hi all!

I'm working on putting infiniband support to main tree. Currently infiniband
related stuff hosted in science overlay in sys-infiniband [1] category (this
category currently contains ~25 packages but they will be ~40) so i wanna move
them as whole category. Also i'm going to add USE_EXPAND for infiniband
userspace drivers:
libmlx4
libmthca
libehca
libcxgb3

Any objections about moving this stuff to tree?

PS some in-tree stuff already has infiniband use flag so i'd like to make it
global or may be rename it to rdma

use will be something like OPENIB_DRIVERS="mlx4 mthca ehca cxgb3"

Honestly i can only tests first two.

Also since mlx4 ib driver wants kernel with xrc support i gonna add 'cluster-
sources' to tree and use flag 'xrc' to virtual/linux-sources-2.6 so sys-
infiniband/libmlx4 will depend on it.

So if there will be no objections i'll proceed with this stuff =)
And I'll move it to tree in an hour or so.



should it be based on the hardware family rather than the lib name ?

i object to it not being done already ! ;)
