On Hyper-V platforms, a slave VF netdev always bonds to Netvsc and remains
as Netvsc's only active slave as long as the slave device is present. This
behavior is the same as a bonded device, but it's not user-configurable.

Some kernel APIs (e.g those in "include/linux/netdevice.h") check for
IFF_MASTER, IFF_SLAVE and IFF_BONDING for determing if those are used in
a master/slave bonded setup. Netvsc's bonding setup with its slave device
falls into this category.

Again, this is way too much of a hack. You're trying to make
netif_is_bond_master() return true for your franken-interfaces
with minimal effort.
