Lorenzo Bianconi 568a3fa24a 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

---help---
If you have a network (Ethernet) card belonging to this class, say Y.
Note that the answer to this question doesn't directly affect the
kernel: saying N will just cause the configurator to skip all
the questions about Marvell devices. If you say Y, you will be
asked for your specific card in the following questions.

tristate "Marvell Discovery (643XX) and Orion ethernet support"
depends on MV64X60 || PPC32 || PLAT_ORION || COMPILE_TEST
depends on INET
select PHYLIB

---help---
This driver supports the gigabit ethernet MACs in the
Marvell Discovery PPC/MIPS chipset family (MV643XX) and
in the Marvell Orion ARM SoC family.
Some boards that use the Discovery chipset are the Momenco
Ocelot C and Jaguar ATX and Pegasos II.
config MVMDIO
tristate "Marvell MDIO interface support"
depends on HAS_IOMEM
select PHYLIB
---help---
This driver supports the MDIO interface found in the network
interface units of the Marvell EBU SoCs (Kirkwood, Orion5x,
Dove, Armada 370 and Armada XP).
This driver is used by the MV643XX_ETH and MVNETA drivers.
config MVNETA_BM_ENABLE
tristate "Marvell Armada 38x/XP network interface BM support"
depends on MVNETA
depends on !64BIT
---help---
This driver supports auxiliary block of the network
interface units in the Marvell ARMADA XP and ARMADA 38x SoC
family, which is called buffer manager.
This driver, when enabled, strictly cooperates with mvneta
driver and is common for all network ports of the devices,
even for Armada 370 SoC, which doesn't support hardware
buffer management.

tristate "Marvell Armada 370/38x/XP/37xx network interface support"
depends on ARCH_MVEBU || COMPILE_TEST
select MVMDIO
select PHYLINK
select PAGE_POOL
---help---
This driver supports the network interface units in the
Marvell ARMADA XP, ARMADA 370, ARMADA 38x and
ARMADA 37xx SoC family.
Note that this driver is distinct from the mv643xx_eth
driver, which should be used for the older Marvell SoCs
(Dove, Orion, Discovery, Kirkwood).

MVNETA_BM must not be 'm' if MVNETA=y, so this symbol ensures
that all dependencies are met.
config MVPP2
tristate "Marvell Armada 375/7K/8K network interface support"

This driver supports the network interface units in the

depends on HAS_IOMEM
depends on CPU_PXA168 || ARCH_BERLIN || COMPILE_TEST
select PHYLIB
---help---
This driver supports the pxa168 Ethernet ports.
To compile this driver as a module, choose M here. The module
will be called pxa168_eth.
config SKGE
tristate "Marvell Yukon Gigabit Ethernet support"
depends on PCI
select CRC32
---help---
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.
config SKGE_DEBUG
bool "Debugging interface"
depends on SKGE && DEBUG_FS
---help---
This option adds the ability to dump driver state for debugging.
The file /sys/kernel/debug/skge/ethX displays the state of the internal
transmit and receive rings.
If unsure, say N.
config SKGE_GENESIS
bool "Support for older SysKonnect Genesis boards"
depends on SKGE
---help---
This enables support for the older and uncommon SysKonnect Genesis
chips, which support MII via an external transceiver, instead of
an internal one. Disabling this option will save some memory
by making code smaller. If unsure say Y.
config SKY2
tristate "Marvell Yukon 2 support"
depends on PCI
select CRC32
---help---
This driver supports Gigabit Ethernet adapters based on the
Marvell Yukon 2 chipset:
Marvell 88E8021/88E8022/88E8035/88E8036/88E8038/88E8050/88E8052/
88E8053/88E8055/88E8061/88E8062, SysKonnect SK-9E21D/SK-9S21
There is companion driver for the older Marvell Yukon and
SysKonnect Genesis based adapters: skge.
To compile this driver as a module, choose M here: the module
will be called sky2. This is recommended.
config SKY2_DEBUG
bool "Debugging interface"
depends on SKY2 && DEBUG_FS
---help---
This option adds the ability to dump driver state for debugging.
The file /sys/kernel/debug/sky2/ethX displays the state of the internal
transmit and receive rings.
If unsure, say N.
