[Kimchi-devel] [PATCH V3 1/3] move _default_network_check from top model to networks model

[shaohef at linux.vnet.ibm.com]

From: ShaoHe Feng <shaohef at linux.vnet.ibm.com>

Top model should load other model and structure preparing.

The default network check is network function, move to networks model
is more reasonable.

And the important: it is more convenient to call attr of networks model
