net: Move some variables to net-common files

2026-01-15T10:09:28+00:00

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.

net: move net_state to net-common

2026-01-15T10:09:28+00:00

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.

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

2025-08-18T13:47:57+00:00

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.

net: lwip: provide net_start_again()

2025-04-23T08:02:49+00:00

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.

net/tcp: add connection info to tcp_stream structure

2024-12-28T17:59:42+00:00

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.

net: lwip: add DHCP support and dhcp commmand

2024-10-16T17:11:56+00:00

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.

net: split net into net{,-common,-legacy,-lwip}

2024-10-16T17:11:56+00:00

Make net.h a wrapper which includes net-common.h and either
net-legacy.h or net-lwip.h based on NET_LWIP. The function
copy_filename() can be useful when NET_LWIP is enabled, therefore
move it out of net/net.c which is built only when networking choice
is NET and create a new file net/net-common.c.
