That's a good point. Anywhere in the receive loops should be OK, for
example right after net_lwip_rx(udev, netif). But for simplicity and
to avoid pattern duplication we may want to call schedule() as well
as sys_check_timeouts() inside net_lwip_rx():
int net_lwip_rx(struct udevice *udev, struct netif *netif)
{
struct pbuf *pbuf;
uchar *packet;
int flags;
int len;
int i;
/* lwIP timers */
sys_check_timeouts();
/* Other tasks and actions */
schedule();
if (!eth_is_active(udev))
return -EINVAL;
...
}
