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 Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: Jesper Dangaard Brouer <brouer@redhat.com> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: David S.

This driver support the Marvell Yukon or SysKonnect SK-98xx/SK-95xx
|
|
and related Gigabit Ethernet adapters. It is a new smaller driver
|
|
with better performance and more complete ethtool support.
|
|
|
|
It does not support the link failover and network management
|
|
features that "portable" vendor supplied sk98lin driver does.
|

This driver supports adapters based on the original Yukon chipset:
|
|
Marvell 88E8001, Belkin F5D5005, CNet GigaCard, DLink DGE-530T,
|
|
Linksys EG1032/EG1064, 3Com 3C940/3C940B, SysKonnect SK-9871/9872.
|
|
|
|
It does not support the newer Yukon2 chipset: a separate driver,
|
|
sky2, is provided for these adapters.
|
|
|
|
To compile this driver as a module, choose M here: the module
|
|
will be called skge. This is recommended.

This enables support for the older and uncommon SysKonnect Genesis
