[PATCH 0/2] Allow dyn pci vector allocation of MANA

In this patchset we want to enable the MANA driver to be able to
allocate MSI vectors in PCI dynamically

The first patch targets the changes required for enabling the support
of dyn vector allocation in pci-hyperv PCI controller. It also consists
of changes in the PCI tree to allow clean support for dynamic allocation
of IRQ vectors for PCI controllers.

The second patch has the changes in MANA driver to be able to allocate
pci vectors dynamically if it is supported by the infra. If the support
does not exist it defaults to older behavior.

For this submission, I wasn't sure if we should specify net-next or pci
tree. Please let me know what the recommendation is.

PCI: hv: enable pci_hyperv to allow dynamic vector allocation
net: mana: Allow MANA driver to allocate PCI vector dynamically
