If the HW indicates support of multiple ports for rdma, create an IB device
with a port per netdev in the ethernet mana driver.
CM is only available on port 1, but RC QPs are supported on all
ports.

Allow mana_ib to be created over ethernet gdma device and
over rnic gdma device. The HW has two devices with different
capabilities and different use-cases. Initialize required

When running under Hyper-V, the master device to the RDMA device is always
bonded to this RDMA device. This is not user-configurable.
The master device can be unbind/bind from the kernel. During those events,
the RDMA device should set to the current netdev to reflect the change of
master device from those events.

Change mana_get_primary_netdev_rcu() to mana_get_primary_netdev(), and
return the ndev with refcount held. The caller is responsible for dropping
the refcount.
Also drop the check for IFF_SLAVE as it is not necessary if the upper
device is present.

Add mana_get_primary_netdev_rcu helper to get a primary
netdevice for a given port. When mana is used with
netvsc, the VF netdev is controlled by an upper netvsc
device. In a baremetal case, the VF netdev is the
primary device.
Use the mana_get_primary_netdev_rcu() helper in the mana_ib
to get the correct device for querying network states.
