How do iSCSI offload HBAs coexist? As I understand it, they typically
just choose a separate IP address.

In any case I'm not going to slip in a patch that another maintainer has
explicitly NAKed. Maybe one way to force things forward would be to
write up an exhaustive explanation of the underlying problem and the
impact on end users, include this patch, explain that it touches only
RDMA code, and point out that most end users are already using this
patch since it's shipped in OFED. Then send the whole thing to Linus
and Andrew Morton, making sure to cc Dave Miller, netdev, and
linux-rdma.
