[gentoo-dev] [RFC] Add support for RDMA enabled devices in main tree

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

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

i object to it not being done already ! ;)

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.

i dont think that's a problem.  no one is expecting you to validate
every piece of hardware.

Why a new category of sys-infiniband vs. existing sys-* categories.
I thought I had seen some existing infiniband packages lurking in the
tree.

Because its very scpecific stuff containing system libs and userspace drivers 
and daemons that will make ib hw functional =)
