When creating a kernel QP where the consumer asked for a send queue with lots of scatter/gater entries, set_kernel_sq_size() incorrectly returned an error if the send queue stride is larger than the hardware's maximum send work request descriptor size. This is not a problem; the only issue is to make sure that the actual descriptors used do not overflow the maximum descriptor size, so check this instead. Clamp the returned max_send_sge value to be no bigger than what query_device returns for the max_sge to avoid confusing hapless users, even if the hardware is capable of handling a few more s/g entries. This bug caused NFS/RDMA mounts to fail when the server adapter used the mlx4 driver. Signed-off-by: Roland Dreier <rolandd@cisco.com> |
