Hello, Vladimir.
Please, apply two patches - libmlx4 and libibverbs - that I sent today.
They add additional enums to userspace to the programs, that need to
use RAW_ETH QP type.
Hi Aleksey,
You should send these patches to Roland before applying them to OFED.
Use the following git trees for libibverbs and libmlx4:
git://git.kernel.org/pub/scm/libs/infiniband/libibverbs.git
git://git.kernel.org/pub/scm/libs/infiniband/libmlx4.git
Note: when you send patches to OFED you should CC "OpenFabrics EWG
<e...@lists.openfabrics.org>" mailing list instead of "linux-rdma".
Regards,
Vladimir
