net: ethernet: Add missing depends on MDIO_DEVRES

2023-04-13T03:38:48+00:00

A number of MDIO drivers make use of devm_mdiobus_alloc_size(). This is only available when CONFIG_MDIO_DEVRES is enabled. Add missing depends or selects, depending on if there are circular dependencies or not. This avoids linker errors, especially for randconfig builds.

net: marvell: Remove reference to CONFIG_MV64X60

2021-03-18T21:19:39+00:00

Commit 92c8c16f3457 ("powerpc/embedded6xx: Remove C2K board support") removed last selector of CONFIG_MV64X60. As it is not a user selectable config item, all references to it are stale. Remove them. Signed-off-by: Christophe Leroy Signed-off-by: David S. Miller

net: mvpp2: Remove unneeded Kconfig dependency.

2021-01-23T21:23:35+00:00

The mvpp2 is an Ethernet driver, and it implements MAC style time stamping of PTP frames. It has no need of the expensive option to enable PHY time stamping. Remove the incorrect dependency. Signed-off-by: Richard Cochran Signed-off-by: Jakub Kicinski

net: marvell: prestera: Add driver for Prestera family ASIC devices

2020-09-17T23:35:46+00:00

Marvell Prestera 98DX326x integrates up to 24 ports of 1GbE with 8 ports of 10GbE uplinks or 2 ports of 40Gbps stacking for a largely wireless SMB deployment. The current implementation supports only boards designed for the Marvell Switchdev solution and requires special firmware. The core Prestera switching logic is implemented in prestera_main.c, there is an intermediate hw layer between core logic and firmware. It is implemented in prestera_hw.c, the purpose of it is to encapsulate hw related logic, in future there is a plan to support more devices with different HW related configurations. This patch contains only basic switch initialization and RX/TX support over SDMA mechanism. Currently supported devices have DMA access range <= 32bit and require ZONE_DMA to be enabled, for such cases SDMA driver checks if the skb allocated in proper range supported by the Prestera device. Also meanwhile there is no TX interrupt support in current firmware version so recycling work is scheduled on each xmit. Port's mac address is generated from the switch base mac which may be provided via device-tree (static one or as nvme cell), or randomly generated. This is required by the firmware.

treewide: replace '---help---' in Kconfig files with 'help'

2020-06-13T16:57:21+00:00

Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada

net: mvneta: introduce page pool API for sw buffer manager

2019-10-21T17:36:07+00:00

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.
