I've got rdma-core building successfully into the yocto build now and it configures correctly. However, when I run any of several test apps that ping between the Arria10 board and a PC, I'm getting nasty segfault errors. The issue appears to be with registration of memory regions. Here's an example when I'm running the server side of a udaddy ping pong test:

root@arria10:~# udaddy -s 10.0.1.16
udaddy: starting client
[ 1883.526301] rdma_rxe: null vaddr
udaddy: connecting
failed to reg MR
udaddy: failed to create messages: -1
test complete
Segmentation fault

I'm running kernel 4.17 and the most recent (v18) version of rdma-core

Thanks,
FM
