Sean-

Here is a patch to allow a local ipv6 address to be resolved by rdma_cm. I reported this in https://bugs.openfabrics.org/show_bug.cgi?id=1759

To reproduce the problem:
rping -s -v -a ::0 &
rping -c -v -a <ipv6 address local to this system> rdma_resolve_addr error -1

Local ipv6 address was obtained with "ip addr show ib0"

Using 'addr' there is clearly wrong, since it's of type struct rdma_dev_addr. Thanks

Quoted 1 line

thanks, applied... I didn't get the original patch but oh well.

The original path was under the subject "Failing to resolve local ipv6 address.'

I changed the subject on my reply.
