rename NET to NET_LEGACY

2026-04-27T17:26:40Z

Highlight that NET really is the legacy networking stack by renaming the option to NET_LEGACY. This requires us to add an SPL_NET_LEGACY alias to SPL_NET as otherwise CONFIG_IS_ENABLED(NET_LEGACY) will not work for SPL. The "depends on !NET_LWIP" for SPL_NET clearly highlights that it is using the legacy networking app so this seems fine to do. This also has the benefit of removing potential confusion on NET being a specific networking stack instead of "any" network stack.

net: Move some variables to net-common files

2026-01-15T10:09:28Z

Make some variables available to be used by either the legacy network code or lwIP by moving them into the net-common files. This also allowed removing a small number of duplicated variables from the lwIP code. Signed-off-by: Andrew Goodbody Reviewed-by: Jerome Forissier

net: move net_state to net-common

2026-01-15T10:09:28Z

Move the net_state variable into common code so that it can be used by either the legacy network code or lwIP. This is needed for porting across the NFS support code for use with lwIP. Signed-off-by: Andrew Goodbody Reviewed-by: Jerome Forissier

net: introduce CONFIG_DNS

Introduce the DNS Kconfig symbol so that various network commands may use host names without the dns command (CMD_DNS) being selected. Signed-off-by: Jerome Forissier CC: E Shattow

net: add missing SPDX-License-Identifier for files originating from LiMon

2025-08-18T13:47:57Z

The header of LiMon imported files reference a License file which does not exist in U-Boot. Some files were forgotten when adding the SPDX-License-Identifier. The LiMon files were originally licensed under GPLv2 as can be seen in commit [2ea91039]. Based on this commit, add the correct SPDX license identifier. While at it drop the reference to the non-existing License file from all LiMon files and update the SPDX-License-Identifier to SPDX version 3. Signed-off-by: Max Merchel

net: lwip: provide net_start_again()

2025-04-23T08:02:49Z

Implement net_start_again() when NET_LWIP=y in a very similar way to NET. This will be used in a future commit to determine if a failed ping needs to be tried again on a different interface. Signed-off-by: Jerome Forissier Reviewed-by: Simon Glass

net/tcp: add connection info to tcp_stream structure

2024-12-28T17:59:42Z

Changes: * Avoid use net_server_ip in tcp code, use tcp_stream data instead * Ignore packets from other connections if connection already created. This prevents us from connection break caused by other tcp stream. Signed-off-by: Mikhail Kshevetskiy Reviewed-by: Simon Glass

net: lwip: add DHCP support and dhcp commmand

2024-10-16T17:11:56Z

Add what it takes to enable NETDEVICES with NET_LWIP and enable DHCP as well as the dhcp command. CMD_TFTPBOOT is selected by BOOTMETH_EFI due to this code having an implicit dependency on do_tftpb(). Note that PXE is likely non-fonctional with NET_LWIP (or at least not 100% functional) because DHCP option 209 is not supported by the lwIP library. Therefore, BOOTP_PXE_DHCP_OPTION cannot be enabled. Signed-off-by: Jerome Forissier Tested-by: Ilias Apalodimas Acked-by: Ilias Apalodimas
