-Subject: [PATCH 2/7] net: mvneta: introduce page pool API for sw buffer
- manager
-
-Use the page_pool api for allocations and DMA handling instead of
-__dev_alloc_page()/dma_map_page() and free_page()/dma_unmap_page().
-Pages are unmapped using page_pool_release_page before packets
-go into the network stack.
-
-The page_pool API offers buffer recycling capabilities for XDP but
-allocates one page per packet, unless the driver splits and manages
-the allocated page.
-This is a preliminary patch to add XDP support to mvneta driver
