This will get a second batch of InfiniBand/RDMA batches.  In addition
to the usual motley crew of changes, this pull includes a new driver
for NetEffect RNICs in drivers/infiniband/hw/nes.  The code could use
some further cleaning, but I don't think it's worth holding off on the
merge.

Does this means ConnectX WQE BB and stateless offload will not be in for 
2.6.25?

What about the patches from Yevgeny supporting our new ConnextX HW 
coming soon?

I talk about:
http://lists.openfabrics.org/pipermail/general/2009-June/060225.html
http://lists.openfabrics.org/pipermail/general/2009-June/060226.html

Since device ID is already in pci.ids I think it is important to have 
this code too, otherwise the driver will not load :-(

MUST also enter the patch I send yesterday:
[PATCH] ipoib: fix kernel Oops resulting from xmit when priv->broadcast is NULL.

(critical bug fix -- will get kernel Oopses whenever ports on the network go down!).
(patch given again below)

- Jack
======================================================================================================================
IPoIB: Fix kernel Oops resulting from xmit following dev_down.

If a port goes down, ipoib_ib_dev_down is invoked -- which flushed the mcasts (clearing
priv->broadcast) and clearing the path record cache. If ipoib_start_xmit is then invoked (before
the port is upped), a kernel Oops results from attempting to access priv->broadcast.

Returning NULL if priv->broadcast is NULL is a harmless way of bypassing the problem -- the
offending packet is simply discarded "without prejudice".
