{net,ib}/mlx5: Don't disable local loopback multicast traffic when needed

2018-01-11T22:52:42Z

There are systems platform information management interfaces (such as HOST2BMC) for which we cannot disable local loopback multicast traffic. Separate disable_local_lb_mc and disable_local_lb_uc capability bits so driver will not disable multicast loopback traffic if not supported. (It is expected that Firmware will not set disable_local_lb_mc if HOST2BMC is running for example.) Function mlx5_nic_vport_update_local_lb will do best effort to disable/enable UC/MC loopback traffic and return success only in case it succeeded to changed all allowed by Firmware. Adapt mlx5_ib and mlx5e to support the new cap bits.

net/mlx5: Fix rate limit packet pacing naming and struct

2017-12-19T21:23:58Z

In mlx5_ifc, struct size was not complete, and thus driver was sending garbage after the last defined field. Fixed it by adding reserved field to complete the struct size. In addition, rename all set_rate_limit to set_pp_rate_limit to be compliant with the Firmware <-> Driver definition.

Pull rdma updates from Doug Ledford: "This is a fairly plain pull request. Lots of driver updates across the stack, a huge number of static analysis cleanups including a close to 50 patch series from Bart Van Assche, and a number of new features inside the stack such as general CQ moderation support. Nothing really stands out, but there might be a few conflicts as you take things in. In particular, the cleanups touched some of the same lines as the new timer_setup changes. Everything in this pull request has been through 0day and at least two days of linux-next (since Stephen doesn't necessarily flag new errors/warnings until day2). A few more items (about 30 patches) from Intel and Mellanox showed up on the list on Tuesday. I've excluded those from this pull request, and I'm sure some of them qualify as fixes suitable to send any time, but I still have to review them fully. If they contain mostly fixes and little or no new development, then I will probably send them through by the end of the week just to get them out of the way. There was a break in my acceptance of patches which coincides with the computer problems I had, and then when I got things mostly back under control I had a backlog of patches to process, which I did mostly last Friday and Monday. So there is a larger number of patches processed in that timeframe than I was striving for.

net/mlx5: QPTS and QPDPM register firmware command support

2017-11-05T04:26:21Z

The QPTS register allows changing the priority trust state between pcp and dscp. Add support to get/set trust state from device. When the port is in pcp/dscp trust state, packet is routed by hardware to matching priority based on its pcp/dscp value respectively. The QPDPM register allow channing the dscp to priority mapping. Add support to get/set dscp to priority mapping from device. Note that to change a dscp mapping, the "e" bit of this dscp structure must be set in the QPDPM firmware command.
