Alex Crawford c820f2b1cf bonding: Add support for probing the bonding module with parameters
Until support for bonding params is added to networkd, this will be
neccessary in order to use bonding parameters (i.e. miimon, mode).
This also makes it such that the 8012q module will only be loaded if
the network config makes use of VLANs.
