2018-05-30net/mlx5e: Get the number of offloaded TC rules from the correct tableOr Gerlitz2-4/+8
As we keep the offloaded TC rules for NIC and e-switch in two different places, make sure to return the number of offloaded flows according to the use-case and not blindly from the priv.

2018-05-29drm/amd/display: Fix BUG_ON during CRTC atomic check updateLeo (Sunpeng) Li1-6/+7
For cases where the CRTC is inactive (DPMS off), where a modeset is not required, yet the CRTC is still in the atomic state, we should not attempt to update anything on it. Previously, we were relying on the modereset_required() helper to check the above condition. However, the function returns false immediately if a modeset is not required, ignoring the CRTC's enable/active state flags. The correct way to filter is by looking at these flags instead.

2018-05-29IB/core: Fix error code for invalid GID entryParav Pandit1-1/+1
When a GID entry is invalid EAGAIN is returned. This is an incorrect error code, there is nothing that will make this GID entry valid again in bounded time. Some user space tools fail incorrectly if EAGAIN is returned here, and this represents a small ABI change from earlier kernels. The first patch in the Fixes list makes entries that were valid before to become invalid, allowing this code to trigger, while the second patch in the Fixes list introduced the wrong EAGAIN. Therefore revert the return result to EINVAL which matches the historical expectations of the ibv_query_gid_type() API of the libibverbs user space library.

David Ahern says: ==================== net: Add address attribute to control metric of prefix route For use cases such as VRR (Virtual Router Redundancy) interface managers want efficient control over the order of prefix routes when multiple interfaces have addresses with overlapping/duplicate subnets. Currently, if two interfaces have addresses in the same subnet, the order of the prefix route entries is determined by the order in which the addresses are assigned or the links brought up. Any actions like cycling an interface up and down changes that order. This set adds a new attribute for addresses to allow a user to specify the metric of the prefix route associated with an address giving interface managers better and more efficient control of the order of prefix routes. Patches 1-3 refactor IPv6 address add functions to pass an ifa6_config struct. The functions currently have a long list of arguments and adding the metric just makes it worse. Because of the overall diff size in moving the arguments to a struct, the change is done in stages to make it easier to review starting with the bottom function and pushing the struct up to callers in each successive patch. Patch 4 introduces the new attribute. Patches 5 and 6 add support for the new attribute to IPv4 and IPv6 addresses. Patch 7 adds a set of test cases. Patch 8 adds support to iproute2 Changes since RFC - collapsed patches 1 and 3 into patch 2 - simplified stack variables in fib_modify_prefix_metric in patch 5 ==================== Signed-off-by: David S.

2018-05-29Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 modelsTakashi Iwai1-7/+25
In commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174") we tried to address the non-working Atheros BT devices by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME. This made such devices working while it turned out to break other existing chips with the very same USB ID, hence it was reverted afterwards. This is another attempt to tackle the issue. The essential point to use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM- patching. And the previous attempt failed because btusb_setup_qca() returns -ENODEV if the ROM version doesn't match with the expected ones. For some devices that have already the "correct" ROM versions, we may just skip the setup procedure and continue the rest. So, the first fix we'll need is to add a check of the ROM version in the function to skip the setup if the ROM version looks already sane, so that it can be applied for all ath devices. However, the world is a bit more complex than that simple solution. Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's 0x0001 at the beginning of probing, so the device probe always aborts here. In this patch, we add another check of ROM version again, and if the device needs patching, the probe continues. For that, a slight refactoring of btusb_qca_send_vendor_req() was required so that the probe function can pass usb_device pointer directly before allocating hci_dev stuff.

Jakub Kicinski says: ==================== nfp: abm: RED/MQ qdisc offload This is second batch of advanced buffer management nfp driver changes. This series adds the qdisc offload. Support for a very simple subset of RED qdisc offload is added as needed for DCTCP ECN marking (min and max thresholds set to the same value). The first two patches fix glitches introduced by the previous series. We have to be careful about phys_port_name handling, because VFs share the same code path, and some user space may get confused by the names we chose. Since unlike previous offloads we can report the queue backlog both in bytes and packets we need to adjust how statistics are added up in the core (patch 6). There are some extra statistics we want to expose which don't fit into TC stats, namely counts of packets which have been fast- -forwarded without getting enqueued because there was no contention and number of packets that were ever queued (sum of all momentary backlogs). We expose those through ethtool stats (patches 8 and 9). Remaining 5 patches add MQ offload - to be able to set different configurations on different queues. Representors are made multi- -queue and we add offload support to MQ. MQ stats are added up before calling ->dump qdiscs on the children, and therefore don't include updated offload values. To avoid clearly incorrect stats MQ is made to also request stats update from offloads. This way we can correct the diff at the driver level. ==================== Signed-off-by: David S.
