    Hello all,

    I've had some problems adding one if_ral interface to if_bridge device.
    I've tracked down the problem to the MTU on my PCI if_ral interface
    which is set to 2290 ( i think that hostapd did this ).

    So, i have a proposition to add some informative printfs to if_bridge code,
    because returning "Invalid argument" is not so self explanatory, especially
    in the wrong MTU case. I think that most of the returns in bridge_ioctl_add(),
    could benefit from additional printf with more information.
    What do you think?
