Some environment variables are relevant for networking. For these U_BOOT_ENV_CALLBACKs have been defined. When the corresponding environment variable is updated the callback updates the state of the network sub-system. In the UEFI subsystem we can use the network even if CONFIG_CMD_NET is not defined. Let the usage of the U_BOOT_ENV_CALLBACKs depend on CONFIG_NET and not on CONFIG_CMD_NET. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
