ib_verbs.h (Roland's branch): Add MAD pointer to send WR ud structure
This is to allow the MAD layer to poke at the MAD header without using
bus_to_virt().

The problem with this is that when this is done on a little endian
machine it shows up byte swapped on the network and not in network
endian.
So if hi_tid = 1 and user tid = 0x9abcdef0

This is the formal announcement on the availability of
the first release of the OpenIB MAD layer with SMI/SMA
(located in the openib-candidate branch).
The OpenIB access layer is comprised of the MAD layer and the SMI/SMA.
These are currently implemented as separate modules. These are layered

Hi,
I'm trying to compile a kernel module which use the VAPI and (maybe) the
CMAPI. And when I compile a file with an inclusion of vapi.h I got this :
Please use the new mthca driver instead of the old mellanox driver.

Great! I will start merging this onto my tree as soon as I get my
IPoIB driver into shape to commit. (I've currently torn it apart
getting rid of the pseudo-ethernet layer, and I have it mostly working
again).

Hi,
Has mthca been tested with Arbel (PCI Express) ? Is this in
compatibility mode or native mode or both ?
Thanks.

I've tested mthca with Arbel in compatibility mode. I haven't had
access to native mode firmware or up-to-date documentation, so I have

Here are some modifications to support timing out send MADs in the access layer. I
haven't tested this code beyond building it, but wanted to make it available for
review. There are a few race conditions that need to be avoided when handling
timeouts, so if it looks like something was missed,

i.e., will it run with an existing PCI-X tavor driver ?

It seems you are using the system-wide keventd queue. This isn't
necessarily a problem per se, but it would probably be better to use a
MAD-layer private workqueue (I suggested a single-threaded workqueue
per MAD port earlier). This avoids two problems. First, keventd is
subject to arbitrary
