Mark Bloch ae43f82867 IB/core: Add IP to GID netlink offload 
There is an assumption that rdmacm is used only between nodes
in the same IB subnet, this why ARP resolution can be used to turn
IP to GID in rdmacm.

When dealing with IB communication between subnets this assumption
is no longer valid. ARP resolution will get us the next hop device
address and not the peer node's device address.

To solve this issue, we will check user space if it can provide the
GID of the peer node, and fail if not.

We add a sequence number to identify each request and fill in the GID
upon answer from userspace.
