RDMA/bnxt_re: Enable low latency push
Introduce driver specific uapi functionalites. Added a alloc_page
functionality for user library to allocate specific pages. Currently added
support for allocating write combine pages for push functinality. This
interface shall be extended for other page allocations.
Allocate a WC page using the uapi hook for enabling the low latency push
in Gen P5 adapters for small packets. This is supported only for the user
space QPs.
