I'm wondering what the status of this patchset is?

Do you get any feedback?

It would be very good if the softiwarp module could be
included in the mainline kernel.

Hopefully Samba will get support for SMB-Direct (SMB2 over RDMA) support
in future. And having RDMA support without hardware support would be very
good for testing and also for usage on the client side against a server
which has hardware RDMA support.

For me at least rping tests work fine using siw.ko on a 3.2.x kernel on
Ubuntu 12.04.
