RDMA/CMA: Use neigh_event_send() to initiate neighbour discovery.
Calling arp_send() to initiate neighbour discovery (ND) doesn't do the
full ND protocol. Namely, it doesn't handle retransmitting the arp
request if it is dropped. The function neigh_event_send() does all this.
Great, thanks !!!
This and the bunch of previous build-related patches
really simplifies the build.

I think GSO is still useful on top of this.
In my patches anything with gso gets put into the batch list and shot
down the driver. Ive never considered checking whether the nic is TSO

Hi Or,
So with ipoib/mthca you still see this 1 : 18.5K retransmission rate
