2025-07-08lwip: move net/lwip/ping.c to cmd/lwipJerome Forissier
Prepare to split the ping command from cmd/net-lwip.c by moving the implementation from net/lwip/dns.c to cmd/lwip. Signed-off-by: Jerome Forissier <jerome.forissier@linaro.org>
2025-07-08net: lwip: call sys_check_timeouts and schedule on rxTim Harvey
Call schedule() in net_lwip_rx() to service U-Boot tasks and actions during packet rx. As a cleanup also move sys_check_timeouts() here and remove it from the functions that call net_lwip_rx(). This resolves the issue of an active watchdog resetting the board on long network activities.

Use net_start_again() in do_ping() to determine if a failed ping should be restarted on a different interface. Signed-off-by: Jerome Forissier <jerome.forissier@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org>
2025-04-23net: lwip: fix initialization sequence before a commandJerome Forissier
The things that are done prior to executing a network command with NET_LWIP are not consistent with what is done with NET. It impacts the selection of the current device, and more precisely if the active device is invalid NET would return an error while NET_LWIP would try to pick a new device. This incorrect behavior was detected thanks to the eth_rotate sandbox test (dm_test_eth_rotate()). Fix it by re-using a sequence similar to what NET has in net_loop(). This piece of code is inserted in a function called net_lwip_eth_start() renamed from net_lwip_eth_set_current().

2025-03-31net: lwip: do_ping() should return CMD_RET_FAILURE when no deviceJerome Forissier
do_ping() expects ping_loop() to return a negative value on error, so that it can propagate it to the caller as CMD_RET_FAILURE. This is not the case when no ethernet device is found, so fix that.

2025-02-12net: lwip: move eth_init() out of new_netif()Jerome Forissier
Move the initialization of the ethernet devices out of the new_netif() function. Indeed, new_netif() accepts a struct device argument, which is expected to be valid and active. The activation and selection of this device are achieved by eth_init() (on first time the network stack is used) and eth_set_current(). This is what takes care of the ethrotate and ethact environment variables. Therefore, move these calls to a new function: net_lwip_set_current(), and use it whenever a net-lwip command is run. This patch hopefully fixes the incorrect net-lwip behavior observed on boards with multiple ethernet interfaces [1]. Tested on an i.MX8MPlus EVK equipped wih two ethernet ports. The dhcp command succeeds whether the cable is plugged into the first or second port.
