This patch is against roland's below Infiniband tree.
http://git.kernel.org/pub/scm/linux/kernel/git/roland/infiniband.git
Simiilar patch against netdev net-next tree will be made based on this patch.

This patch adds functionality to support RoCE (RDMA over Ethernet) driver.
- Detecting RoCE supported adapters and creating linked list of them.
- Enabling 5 more MSIX vectors for RoCE functionality.
- Calling registered callback functions of the RoCE driver
 whenever new RoCE capable device is added/removed.
- Notifying events to RoCE driver when interface is up or down.
- Provides device specific details to RoCE driver for each roce device.
- Provides low level mailbox command to be issued by RoCE driver
 before it can have it own MQ.

 be2net: Added functionality to support RoCE driver

Great, I'm really excited to be getting another upstream driver.

I would suggest that when the actual RoCE driver is posted, we
merge these 2 prerequisite patches + the driver through my tree,
to avoid the hassle of a dependency between my tree and Dave's
net-next tree.

(Assuming these patches are OK with Dave and everyone else...
they look pretty reasonable to me after a quick read)

When do you expect to post the actual RoCE driver?  If that's
going to be a while, another possibility is to just merge these
patches through net-next for 3.4, although I'm not sure about
how Dave feels about merging all this stuff without seeing what
will actually use it.

Thanks,
  Roland
