Subject: IB/srpt: Set srq_type to IB_SRQT_BASIC
From: Roland Dreier <[email protected]>
commit 6f3603367b8f7c34598fdfc1058622e0e1951e98 upstream.
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)
