[openib-general] [PATCH] netdevice.h: Add RDMA private pointer to the net_device structure

[Caitlin Bestler]

I've been trying to think of some iWARP uses, but haven't
come up with any yet. But I have strong lingering suspicions
that they will eventually be found and having this type of
field will ensure that the data is placed where it belongs
rather than another inappropriate peeking at another layer's
data being the result.
