From 8cb330355bd52852f209cf08c1e79babfbdf1253 Mon Sep 17 00:00:00 2001 From: Jerome Forissier Date: Wed, 16 Oct 2024 12:03:59 +0200 Subject: net: introduce alternative implementation as net/lwip/ Prepare the introduction of the lwIP (lightweight IP) TCP/IP stack by adding a new net/lwip/ directory and the NET_LWIP symbol. Network support is either NO_NET, NET (legacy stack) or NET_LWIP. Subsequent commits will introduce the lwIP code, re-work the NETDEVICE integration and port some of the NET commands and features to lwIP. SPL_NET cannot be enabled when NET_LWIP=y. SPL_NET pulls some symbols that are part of NET (such as arp_init(), arp_timeout_check(), arp_receive(), net_arp_wait_packet_ip()). lwIP support in SPL may be added later. Similarly, DFU_TFTP and FASTBOOT are not compatible with NET_LWIP because of dependencies on net_loop(), tftp_timeout_ms, tftp_timeout_count_max and other NET things. Let's add a dependency on !NET_LWIP for now. SANDBOX can select NET_LWIP but doing so will currently disable the eth dm tests as well as the wget tests which have strong dependencies on the NET code. Other adjustments to Kconfig files are made to fix "unmet direct dependencies detected" for USB_FUNCTION_SDP and CMD_FASTBOOT when the default networking stack is set to NET_LWIP ("default NET_LWIP" instead of "default NET" in Kconfig). The networking stack is now a choice between NO_NET, NET and NET_LWIP. Therefore '# CONFIG_NET is not set' should be 'CONFIG_NO_NET=y'. Adjust the defconfigs accordingly.
