Currently the HFI and QIB drivers allow the IB core to assign a unit number to the driver name string. If multiple devices exist in a system, there is a possibility that the device unit number and the IB core number will be mismatched. Fix by using the driver defined unit number to generate the device name. Reviewed-by:

When the rdmavt's RNRNAK timer is fired, it tries to cancel the timer by calling hrtimer_try_to_cancel(), which always returns -1 because the timer is currently running. This patch removes this useless call. Reviewed-by:

Today we have single function which is used when we add an IB interface, break this function into multiple functions. Create stages and a generic mechanism to execute each stage. This is in preparation for RDMA/IB representors which might not need all stages or will do things differently in some of the stages. This patch doesn't change any functionality. Signed-off-by:

This patch exposes the option to dynamic allocates a UAR, this functionality will be used in downstream patch in this series as part of QP creation. Specifically, the user space driver asks for a UAR allocation in a given page index, upon success this UAR and its bfregs can be used as part of QP creation by the user space driver. To enable allocating more than 256 UARs the page index is encoded in an extra one byte just after the command byte. Signed-off-by:

This patch extends the alloc context flow to be prepared for working with dynamic UAR allocations. Currently upon alloc context there is some fix size of UARs that are allocated (named 'static allocation') and there is no option to user application to ask for more or control which UAR will be used by which QP. In this patch the driver prepares its data structures to manage both the static and the dynamic allocations and let the user driver knows about the max value of dynamic blue-flame registers that are allowed. Downstream patches from this series will enable the dynamic allocation and the association as part of QP creation. Signed-off-by:
