BACH NIC Configuration for VLAN setup

This is the tentative setup for BACH to run VLANs:

2 NICs:

• B57_1_EII: the board is for the default network (172.16.0.0/16), and should be teamed up with the other NIC once the VLAN is setup.
• B57_2_EII: the board is for VLAN setup. All networks go to this NIC and a DHCP server serves here
