[ofa-general] InfiniBand/iWARP/RDMA merge plans for 2.6.26 (what's in infiniband.git)

[Roland Dreier]

The 2.6.26 will open soon, so it's time to review what my plans are
for the merge window opens.

As usual, patch review by non-me people is always welcome.

Anyway, here are all the pending things that I'm aware of.  As usual,
if something isn't already in my tree and isn't listed below, I
probably missed it or dropped it by mistake.  Please remind me again
in that case.

Core:

 - I did a bunch of cleanups all over drivers/infiniband and the
   gcc and sparse warning noise is down to a pretty reasonable level.
   Further cleanups welcome of course.

ULPs:

 - I merged Eli's IPoIB stateless offload changes for checksum
   offload and LSO changes.  The interrupt moderation changes are
   next, and should not be a problem to merge.  Please test IPoIB
   on all sorts of hardware!

 - Shirley's IPoIB 4 KB MTU changes.  I expect these to make it in,
   although I would certainly appreciate review from Eli or anyone else.

HW specific:

 - Vlad's mlx4 resize CQ support.  Looks basically OK, so I think we
   should be able to get it in.

 - ipath support for 7220 HCAs.  I don't expect any issues here once
   the patches appear.

Here are a few topics that I believe will not be ready in time for the
2.6.26 window and will need to wait for 2.6.27 at least:

 - XRC.  I still don't have a good feeling that we have settled on all
   the nuances of the ABI we want to expose to userspace for this, and
   ideally I would like to understand how ehca LL QPs fit into the
   picture as well.

 - Remove LLTX from IPoIB.  I haven't had time to finish this yet, so
   I guess it will probably wait for 2.6.27 now...

 - Multiple CQ event vector support.  I still haven't seen any
   discussions about how ULPs or userspace apps should decide which
   vector to use, and hence no progress has been made since we
   deferred this during the 2.6.23 merge window.
