    Agreed. I noticed this issue, too, but forgot about it later.
    Would you mind filing a PR with me in Cc so that I won't forget
    about it again? Can't promise making the order arbitrary, but
    documenting this subtlety is a must.

    Just use:

      ifconfig_vlan14="inet W.X.Y.Z netmask 255.255.255.0 vlan 14 vlandev fxp0"

    This is what ifconfig(8) manpage tells in the syntax section:
    the address should precede other parameters.
