IB/hfi1: Activate the dummy netdev As described in earlier patches, ipoib netdev will share receive contexts with existing VNIC netdev through a dummy netdev. The following changes are made to achieve that: - Set up netdev receive contexts after user contexts. A function is added to count the available netdev receive contexts. - Add functions to set/get receive map table free index. - Rename NUM_VNIC_MAP_ENTRIES as NUM_NETDEV_MAP_ENTRIES. - Let the dummy netdev own the receive contexts instead of VNIC. - Allocate the dummy netdev when the hfi1 device is added and free it when the device is removed. - Initialize AIP RSM rules when the IpoIb rxq is initialized and remove the rules when it is de-initialized. - Convert VNIC to use the dummy netdev.

IB/hfi1: Decouple IRQ name from type IRQ name was connected to IRQ type, this is not sufficient and it would be better to use name as argument to msix_request_irq instead of assigning it to variables when function is called. Index argument was required to generate name and now it can be removed. To generate name correctly helpers function were added and updated.

IB/hfi1: Rework the IRQ API to be more flexible The current IRQ API is an all or nothing interface. This has two problems: 1. All IRQs are enabled regardless of use 2. Moving from general interrupt to MSIx handling is difficult Introduce a new API to enable/disable specific IRQs or a range of IRQs. Do not enable and disable all IRQs in one step. Rework various modules to enable/disable IRQs when needed.
