2016-10-07ipoib: Make ipoib_warn ratelimitedkernel@kyup.com1-1/+7
In certain cases it's possible to be flooded by warning messages. To cope with such situations make the ipoib_warn macro be ratelimited. To prevent accidental limiting of legitimate, bursty messages make the limit fairly liberal by allowing up to 100 messages in 10 seconds.

alloc_ordered_workqueue() with WQ_MEM_RECLAIM set, replaces deprecated create_singlethread_workqueue(). This is the identity conversion.

WQ_MEM_RECLAIM has been set since the flush operations may need to complete in order for other network functions to continue, and the memory reclaim operation might need the network functioning in order to make progress.

Flow steering specifications structures were implemented as in an extensible way that allows one to add new filters and new fields to existing filters. These specifications have never been extended, therefore the kernel flow specifications size and the user flow specifications size were must to be equal. In downstream patch, the IPv4 flow specifications type is extended to support TOS and TTL fields. To support an extension we change the flow specifications size condition test to be as following: * If the user flow specifications is bigger than the kernel specifications, we verify that all the bits which not in the kernel specifications are zeros and the flow is added only with the kernel specifications fields. * Otherwise, we add flow rule only with the user specifications fields.

2016-09-23IB/core: remove ib_get_dma_mrChristoph Hellwig2-38/+8
We now only use it from ib_alloc_pd to create a local DMA lkey if the device doesn't provide one, or a global rkey if the ULP requests it. This patch removes ib_get_dma_mr and open codes the functionality in ib_alloc_pd so that we can simplify the code and prevent abuse of the functionality. As a side effect we can also simplify things by removing the valid access bit check, and the PD refcounting. In the future I hope to also remove the per-PD global MR entirely by shifting this work into the HW drivers, as one step towards avoiding the struct ib_mr overload for various different use cases.
