IB/srpt: Set srq_type to IB_SRQT_BASIC
Since commit 96104eda0169 ("RDMA/core: Add SRQ type field"), kernel users of SRQs need to specify srq_type = IB_SRQT_BASIC in struct ib_srq_init_attr, or else most low-level drivers will fail in when srpt_add_one() calls ib_create_srq() and gets -ENOSYS. (mlx4_ib works OK nearly all of the time, because it just needs srq_type != IB_SRQT_XRC. And apparently nearly everyone using ib_srpt is using mlx4 hardware) Reported-by: Alexey Shvetsov <alexxy@gentoo.org> Cc: <stable@vger.kernel.org> Signed-off-by: Roland Dreier <roland@purestorage.com>
