octeontx2-pf: Add support for page pool
[ Upstream commit
b2e3406a38f0f48b1dfb81e5bb73d243ff6af179 ]
Page pool for each rx queue enhance rx side performance
by reclaiming buffers back to each queue specific pool. DMA
mapping is done only for first allocation of buffers.
As subsequent buffers allocation avoid DMA mapping,
it results in performance improvement.
