This means\nthat if NET is enabled, either the legacy or lwIP stack is necessarily\nselected, which allows us to simplify if NET_LEGACY || NET_LWIP into\nif NET in a later commit.\n\nConfig fragments - or defconfigs including other defconfigs - setting\nthe network stack (NET_LEGACY or NET_LWIP) must also set NET (or unset\nNO_NET) if the config they apply to - or the included defconfigs -\nunsets NET (or selects NO_NET) as otherwise the NET_LEGACY and NET_LWIP\nsymbols are unreachable. This is the case for the two defconfig modified\nin this commit.\n\nNO_NET is now a convenience symbol which hides NET entirely to avoid\nmodifying many defconfigs. If one selected NO_NET to disable the\nnetworking stack in the past, this will still work for now. Technically,\nwe should be using the \"transitional\" Kconfig attribute but that is only\navailable since Kconfig from Linux kernel v6.18 and we're on 6.1 right\nnow.\n\nNote that this moves CONFIG_SYS_RX_ETH_BUFFER from under the Network\nmenu back into the main menu as it seems like it needs to be defined\neven when there's no need for NET support at all and menuconfig option\ndoesn't work the same way as a menu.\n\nSigned-off-by: Quentin Schulz \n---\n\nI'd say we should have everything net-related depends on NET as well,\nso that disabling networking support with NET=n is also disabling\nanything related (e.g. Ethernet controller and PHY drivers, USB\nEthernet, USB gadget CDC/RNDIS, network CLI commands, etc.).\n---\n configs/am62px_evm_r5_ethboot_defconfig | 2 +-\n configs/j722s_evm_r5_ethboot_defconfig | 2 +-\n net/Kconfig | 23 ++++++++++++-----------\n 3 files changed, 14 insertions(+), 13 deletions(-)","diff":"diff --git a/configs/am62px_evm_r5_ethboot_defconfig b/configs/am62px_evm_r5_ethboot_defconfig\nindex 8baec9d43ff..df49324b25a 100644\n--- a/configs/am62px_evm_r5_ethboot_defconfig\n+++ b/configs/am62px_evm_r5_ethboot_defconfig\n@@ -5,7 +5,7 @@ CONFIG_ARCH_K3=y\n CONFIG_SOC_K3_AM62P5=y\n CONFIG_TARGET_AM62P5_R5_EVM=y\n CONFIG_DEFAULT_DEVICE_TREE=\"k3-am62p5-r5-sk\"\n-CONFIG_NET_LEGACY=y\n+# CONFIG_NO_NET is not set\n CONFIG_SPL_BOARD_INIT=y\n CONFIG_SPL_DMA=y\n CONFIG_SPL_ENV_SUPPORT=y\ndiff --git a/configs/j722s_evm_r5_ethboot_defconfig b/configs/j722s_evm_r5_ethboot_defconfig\nindex e4682edb455..cc71f913d3c 100644\n--- a/configs/j722s_evm_r5_ethboot_defconfig\n+++ b/configs/j722s_evm_r5_ethboot_defconfig\n@@ -5,7 +5,7 @@ CONFIG_ARCH_K3=y\n CONFIG_SOC_K3_J722S=y\n CONFIG_TARGET_J722S_R5_EVM=y\n CONFIG_DEFAULT_DEVICE_TREE=\"k3-j722s-r5-evm\"\n-CONFIG_NET_LEGACY=y\n+# CONFIG_NO_NET is not set\n CONFIG_SPL_DRIVERS_MISC=y\n CONFIG_SPL_BOARD_INIT=y\n CONFIG_SPL_DMA=y\ndiff --git a/net/Kconfig b/net/Kconfig\nindex 89d949b5f2c..e712a0dd2ac 100644\n--- a/net/Kconfig\n+++ b/net/Kconfig\n@@ -2,17 +2,22 @@\n # Network configuration\n #\n \n-menu \"Networking\"\n+config NO_NET\n+\tbool \"Disable networking\"\n+\thelp\n+\t Transitional variable.
