net: guard SYS_RX_ETH_BUFFER with NET

2026-06-03T14:55:55Z

SYS_RX_ETH_BUFFER represents the number of Ethernet receive packet buffers. It therefore doesn't make sense it's reachable if NET isn't enabled. Direct users of SYS_RX_ETH_BUFFER are: - drivers/net/rtl8169.c, only compiled if CONFIG_RTL8169=y, depends on CONFIG_NETDEVICES=y, depends on CONFIG_NET=y, - drivers/net/fsl_enetc.h, via ENETC_BD_CNT, included in drivers/net/{fsl_enetc.c,fsl_enetc_mdio.c,mscc_eswitch/felix_switch.c} First two only compiled if CONFIG_FSL_ENETC=y, latter with CONFIG_MSCC_FELIX_SWITCH=y. Both symbols depends on CONFIG_NETDEVICES=y, depends on CONFIG_NET=y. - include/net-common.h via PKTBUFSRX, Indirect users via PKTBUFSRX: - arch/sandbox/include/asm/eth.h - according to ./tools/qconfig.py -l -f CONFIG_SANDBOX CONFIG_NO_NET, all sandbox defconfigs have network enabled so ignore this for now, - drivers/dma/ti/k3-udma.c - sets UDMA_RX_DESC_NUM to that if defined, else 4. PKTBUFSRX is CONFIG_SYS_RX_ETH_BUFFER which defaults to 4. According to ./tools/qconfig.py -l -f CONFIG_TI_K3_NAVSS_UDMA '~CONFIG_SYS_RX_ETH_BUFFER=4' no defconfig enabling this DMA driver sets CONFIG_SYS_RX_ETH_BUFFER to anything but the default of 4, so regardless of NET being built UDMA_RX_DESC_NUM will always be 4 with current defconfigs. - drivers/net/{airoha_eth.c,bcm6348-eth.c,bcm6368-eth.c,cortina_ni.c, dc2114x.c,eepro100.c,essedma.c,ethoc.c,ftgmac100.c,ftmac100.c, hifemac.c,mcffec.c,mpc8xx_fec.c,pic32_eth.c,sandbox.c,sni_ave.c, sni_netsec.c,ti/am65-cpsw-nuss.c,ti/cpsw.c,ti/icssg_prueth.c, tsec.c} all depends on CONFIG_NETDEVICES=y, depends on CONFIG_NET=y, - net/lwip/net-lwip.c, only compiled if CONFIG_NET_LWIP=y, depends on CONFIG_NET=y, - net/{net.c,tcp.c}, only compiled if CONFIG_NET_LEGACY=y, depends on CONFIG_NET=y, - net/net-common.c, only compiled if CONFIG_NET=y, - test/cmd/wget.c, only compiled if CONFIG_NET_LEGACY=y, depends on CONFIG_NET=y, - test/image/spl_load_net.c, only compiled if CONFIG_SPL_UT_LOAD_NET=y, depends on CONFIG_SPL_ETH=y, depends on CONFIG_SPL_NET=y, depends on CONFIG_NET_LEGACY=y, depends on CONFIG_NET=y, Indirect users via net_rx_packets[PKTBUFSRX].

simplify NET_LEGACY || NET_LWIP condition with NET condition

2026-04-27T17:26:40Z

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.

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

bootstd: make it possible to use tftp for netboot with standardboot

2025-10-24T19:47:50Z

Add the option to load the bootscript with the tftp command (static IP) instead of the dhcp command (dynamic IP). For this a new function tftpb_run similar to dhcp_run, is needed. The selection of which command to use can be done with the ip_dyn environment variable, which can be set to yes or no. The ip_dyn variable was chosen as it is already in use on the imx platforms. Also edit the bootstd doc. Reviewed-by: Simon Glass Signed-off-by: Benjamin Hahn

net: make dhcp_run() common for NET and NET_LWIP

2025-10-22T12:28:33Z

There are currently two implementations of dhcp_run(): one in cmd/net.c for NET and one in net/lwip/dhcp.c for NET_LWIP. There is no justification for that. Therefore, move the NET version into net/net-common.c to be used by both stacks, and drop the NET_LWIP version which by the way does not look totally correct.

net: extract function net_sntp_set_rtc() from sntp_handler()

2025-07-08T09:07:37Z

Extract the code that sets the RTC clock from sntp_handler() in net/sntp.c and make it a new function net_sntp_set_rtc() in net/net-common.c. This will allow re-use with NET_LWIP. According to [1] it is safe to assume that all devices have been converted to DM_RTC so drop the useless code.

Merge patch series "Remove from "

2025-05-29T14:31:07Z

Tom Rini says: Hey all, This is a v3 of Simon's series[1] and depends on the series[2] I posted the other day that removes from . With this series done, I believe we've tackled all of the current cases of headers which include without directly needing it. Much of this series is in fact Simon's v2 with the main differneces being: - Removing from at the end - Removing env_to_ip() given how little it's used rather than shuffling around where it's declared and un-inline'ing it. For a rarely used helper, this ends up being cleaner I think. Especially looking at some of the users (which called env_get repeatedly). If there's strong opinion here about using the other method[3] we can do that instead. - Setting aside for now how to handle CMD_ELF=y and NO_NET=y because today it's actually fine as we unconditionally build lib/net_utils.c where string_to_ip() is defined. I'm unsure if a further series is warranted here or not. We rely on link-time optimization to keep code readable too.
