RDMA/hns: Remove unsupport cmdq mode
CMDQ support un-interrupt mode only, and firmware ignores this mode flag, so remove it. Fixes: a04ff739f2a9 ("RDMA/hns: Add command queue support for hip08 RoCE driver") Link: https://lore.kernel.org/r/1629539607-33217-2-git-send-email-liangwenpeng@huawei.com Signed-off-by: Lang Cheng <chenglang@huawei.com> Signed-off-by: Wenpeng Liang <liangwenpeng@huawei.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
