From: Quentin Schulz <quentin.schulz@cherry.de>
In the main Kconfig, there are only two more menus, General Setup and
Expert, in addition to the net menu. Since the part in the main Kconfig
is mostly about selecting the network stack (legacy or lwIP), and that
we already have a net/Kconfig, let's move those to net/Kconfig to have
everything in the same place.
No intended change in behavior.

From: Quentin Schulz <quentin.schulz@cherry.de>
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.

This patch series is about renaming stuff, not fixing stuff (though you
can see some trivial "fixes" in patch 5 and 6).
I agree with you that this needs to be switched to (new) CONFIG_NET.
I'll try to not forget adding it to a v2 (as a separate patch) if
there's a need for one, or send a follow-up patch.

See above. This one seems ok, but I am not really planning to modify
individual boards that I cannot test. This change would mean in a way
that CONFIG_NET_LWIP has been tested with that board, which possibly
isn't the case and I cannot guarantee that either.

OK, fair enough. This is worth a follow-up though, as having
NET_LEGACY about the place suggests that the code is old.

From: Quentin Schulz <quentin.schulz@cherry.de>
This will allow a bunch of simplifications across the code base.
Disabling NET is the equivalent of today's NO_NET choice. This means
that if NET is enabled, either the legacy or lwIP stack is necessarily
selected, which allows us to simplify if NET_LEGACY || NET_LWIP into
if NET in a later commit.
Config fragments - or defconfigs including other defconfigs - setting
the network stack (NET_LEGACY or NET_LWIP) must also set NET (or unset
NO_NET) if the config they apply to - or the included defconfigs -
unsets NET (or selects NO_NET) as otherwise the NET_LEGACY and NET_LWIP
symbols are unreachable. This is the case for the two defconfig modified
in this commit.
NO_NET is now a convenience symbol which hides NET entirely to avoid
modifying many defconfigs. If one selected NO_NET to disable the
networking stack in the past, this will still work for now. Technically,
we should be using the "transitional" Kconfig attribute but that is only
available since Kconfig from Linux kernel v6.18 and we're on 6.1 right
now.
Note that this moves CONFIG_SYS_RX_ETH_BUFFER from under the Network
menu back into the main menu as it seems like it needs to be defined
even when there's no need for NET support at all and menuconfig option
doesn't work the same way as a menu.

I'd say we should have everything net-related depends on NET as well,
so that disabling networking support with NET=n is also disabling
anything related (e.g. Ethernet controller and PHY drivers, USB
Ethernet, USB gadget CDC/RNDIS, network CLI commands, etc.).

Does this imply that NET_LEGACY is the default? Choosing LEGACY as default would not be plausible to me. We should use LWIP as default. Then every new board will use it, hopefully.

(below, "current" means the value in master branch, so before this
series is applied).
(current) CONFIG_NET is the default already, see
https://source.denx.de/u-boot/u-boot/-/blob/master/Kconfig#L794-L824.
This series does not aim to change anything but the name of the symbols.
Yes, we could make NET_LWIP the new default stack, but not in this
series. Also, we have an issue that if you enable SPL_NET you need the
legacy stack, even in proper (according to
https://source.denx.de/u-boot/u-boot/-/blob/master/common/spl/Kconfig#L1152-L1154).
So we would need to tackle this first (we don't necessarily need to
support lwIP in SPL, just that the choice in SPL shouldn't impact the
choice in proper).
If you're asking about this defconfig specifically, it's simply because
it is not a typical defconfig. It includes
configs/am62px_evm_r5_defconfig which sets CONFIG_NO_NET=y. Because
NO_NET used to (before this series) be a choice with (current) NET and
NET_LWIP, am62px_evm_r5_ethboot_defconfig needed to override it with
another choice, namely (current) NET. Because NET_LEGACY is
automatically selected when NO_NET is unset (due to NET default y), we
only need to unset NO_NET in configs/am62px_evm_r5_ethboot_defconfig to
restore the current state of enabling the legacy stack (current NET, now
NET_LEGACY). This is not changing anything, just moving things around.
Does this answer your question?
Cheers,
Quentin

Since the move to make NET a menuconfig and NO_NET a synonym of NET=n,
when NET is enabled, NET_LEGACY || NET_LWIP is necessarily true, so
let's simplify the various checks across the codebase.
SPL_NET_LWIP doesn't exist but SPL_NET_LEGACY is an alias for SPL_NET so
the proper symbol is still defined in SPL whenever needed.

NO_NET is now a transitional symbol which may eventually be removed. Its
meaning is the opposite of the new meaning of NET (that is, any
networking stack).
Update the symbol dependency by using NET instead of !NO_NET.

Thanks for this cleanup!
Re SYS_RX_ETH_BUFFER, how about moving the extern for net_rx_packets[]
to net-legacy.h ? (is it used with lwip?)

That's not the only thing making use of SYS_RX_ETH_BUFFER.
- drivers/net/fsl_enetc.h uses it as value for ENETC_BD_CNT which is
used in drivers/net/fsl_enetc.c,
- drivers/net/rtl8169.c uses it (if defined, otherwise defaults to 4) to
create a static buffer, see NUM_RX_DESC,
- include/net-common.h sets PKTBUFSRX to it, this in turn is used in
*many* places, including many network (assumed Ethernet controller)
drivers, net/lwip/net-lwip.c, net/net-common.c (with net_rx_packets
array, used all over the place), net/net.c, and net/tcp.c.
So seems to be used for both NET_LEGACY and NET_LWIP.
Simply guarding the "#include <net-common.h>" with
CONFIG_IS_ENABLED(NET) won't do as many files currently expect some
functions/macros/constants from that header to be defined.
Another option is to ifdef PKTBUFSRX contant and net_rx_packets array in
include/net-common.h. But it's used in arch/sandbox/include/asm/eth.h
and drivers/dma/ti/k3-udma.c which aren't clearly dpeending on NET being
set. All defconfigs enabling CONFIG_TI_K3_NAVSS_UDMA do not modify the
default CONFIG_SYS_RX_ETH_BUFFER which is 4 (according to
./tools/qconfig.py -l -f CONFIG_TI_K3_NAVSS_UDMA
'~CONFIG_SYS_RX_ETH_BUFFER=4') so it should be fine for this driver not
to have PKTBUFSRX defined (as UDMA_RX_DESC_NUM will then default to 4).
According to ./tools/qconfig.py -l -f CONFIG_SANDBOX CONFIG_NO_NET, all
sandbox defconfigs have network enabled so maybe
arch/sandbox/include/asm/eth.h is not an issue either (or rather, for
later :) ).

Yes that approach seems good, definitely a separate series as you say.
