Enables the use of multiple transmit and receive scrqs allowing the ibmvnic
driver to take advantage of multiqueue functionality. To achieve this, the
driver must implement the process of negotiating the maximum number of
queues allowed by the server. Initially, the driver will attempt to login
with the maximum number of tx and rx queues supported by the server. If
the server fails to allocate the requested number of scrqs, it will return
partial success in the login response. In this case, we must reinitiate
the login process from the request capabilities stage and attempt to login
requesting fewer scrqs.

The switchdev design implies that a software error should not happen in
the commit phase since it must have been previously reported in the
prepare phase. If an hardware error occurs during the commit phase,
there is nothing switchdev can do about it.
The DSA layer separates port_vlan_prepare and port_vlan_add for
simplicity and convenience. If an hardware error occurs during the
commit phase, there is no need to report it outside the driver itself.
Make the DSA port_vlan_add routine return void for explicitness.

When changing MTU on running device first allocate new rings
and buffers and once it succeeds proceed with changing MTU.
Allocation of new rings is not really necessary for this
operation - it's done to keep the code simple and because
size of the extra ring memory is quite small compared to
the size of buffers.
Operation can still fail midway through if FW communication
times out. In that case we retry with old MTU (rings).

Similar to TX side clean up the spill of functionality

RX ring reset does not free buffers from the ring.
Ring reset means only that FW pointers are zeroed and
buffers on the ring must be placed in [0, cnt - 1)
