RDMA/ipoib: Add support for XDR speed in ethtool

2023-09-26T09:38:57Z

The IBTA specification 1.7 has new speed - XDR, supporting signaling rate of 200Gb. Ethtool support of IPoIB driver translates IB speed to signaling rate. Added translation of XDR IB type to rate of 200Gb Ethernet speed.

IB: move from strlcpy with unused retval to strscpy

2022-08-21T11:18:02Z

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

ethtool: extend coalesce setting uAPI with CQE mode

2021-08-24T14:38:29Z

In order to support more coalesce parameters through netlink, add two new parameter kernel_coal and extack for .set_coalesce and .get_coalesce, then some extra info can return to user with the netlink API. Signed-off-by: Yufeng Mo Signed-off-by: Huazhong Tan Signed-off-by: Jakub Kicinski

RDMA/ipoib: Add 50Gb and 100Gb link speeds to ethtool

2020-11-02T19:48:56Z

The IBTA specification has new speeds - HDR and NDR, supporting signaling rate of 50Gb and 100Gb respectively. ethtool support of ipoib driver translates IB speed to signaling rate. Added translation of HDR and NDR IB types to rates of 50Gb and 100Gb ethernet speed.

Pull rdma updates from Jason Gunthorpe: "The majority of the patches are cleanups, refactorings and clarity improvements. This cycle saw some more activity from Syzkaller, I think we are now clean on all but one of those bugs, including the long standing and obnoxious rdma_cm locking design defect. Continue to see many drivers getting cleanups, with a few new user visible features. Summary: - Various driver updates for siw, bnxt_re, rxe, efa, mlx5, hfi1 - Lots of cleanup patches for hns - Convert more places to use refcount - Aggressively lock the RDMA CM code that syzkaller says isn't working - Work to clarify ib_cm - Use the new ib_device lifecycle model in bnxt_re - Fix mlx5's MR cache which seems to be failing more often with the new ODP code - mlx5 'dynamic uar' and 'tx steering' user interfaces" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (144 commits) RDMA/bnxt_re: make bnxt_re_ib_init static IB/qib: Delete struct qib_ivdev.qp_rnd RDMA/hns: Fix uninitialized variable bug RDMA/hns: Modify the mask of QP number for CQE of hip08 RDMA/hns: Reduce the maximum number of extend SGE per WQE RDMA/hns: Reduce PFC frames in congestion scenarios RDMA/mlx5: Add support for RDMA TX flow table net/mlx5: Add support for RDMA TX steering IB/hfi1: Call kobject_put() when kobject_init_and_add() fails IB/hfi1: Fix memory leaks in sysfs registration and unregistration IB/mlx5: Move to fully dynamic UAR mode once user space supports it IB/mlx5: Limit the scope of struct mlx5_bfreg_info to mlx5_ib IB/mlx5: Extend QP creation to get uar page index from user space IB/mlx5: Extend CQ creation to get uar page index from user space IB/mlx5: Expose UAR object and its alloc/destroy commands IB/hfi1: Get rid of a warning RDMA/hns: Remove redundant judgment of qp_type RDMA/hns: Remove redundant assignment of wc->smac when polling cq RDMA/hns: Remove redundant qpc setup operations RDMA/hns: Remove meaningless prints ...

RDMA/ipoib: Remove check for ETH_SS_TEST

2019-06-11T23:00:10Z

The default action for unlisted tests is "not-supported", so given that ipoib doesn't support ETH_SS_TEST, there is no need to check for it in the case statements, just let it get caught by the default: case.
