Add guidelines in Kconfig explaining the minimum required MQTT_SN_LIB_MAX_ADDR_SIZE for UDP transport and IPv4 and or IPv6. Also explain when this value might need to be changed. Use these values to provide a sane default for IPv4 and IPv6. Signed-off-by: Aurelien Jarno <[email protected]>
Introduce BUILD_ASSERT checks in the UDP transport implementation to ensure the configured maximum address size is large enough for the enabled IP families. Signed-off-by: Aurelien Jarno <[email protected]>
