When a devlink port is unregistered, its type is expected to be unset or
otherwise a WARNING is generated [1]. This was supposed to be handled by
cited commit by clearing the type upon 'NETDEV_PRE_UNINIT'.

The assumption was that no other events can be generated for the netdev
after this event, but this proved to be wrong. After the event is
generated, netdev_wait_allrefs_any() will rebroadcast a
'NETDEV_UNREGISTER' until the netdev's reference count drops to 1. This
causes devlink to set the port type back to Ethernet.

Fix by only setting and clearing the port type upon 'NETDEV_POST_INIT'
and 'NETDEV_PRE_UNINIT', respectively. For all other events, preserve
the port type.

If ethtool_ops::get_drvinfo() callback isn't set,
ethtool_get_drvinfo() will fill the ethtool_drvinfo::name and
ethtool_drvinfo::bus_info fields.

However, if the driver provides the callback function, those two
fields are not touched. This means that the driver has to fill these
itself.

Allow the driver to leave those two fields empty and populate them in
such case. This way, the driver can rely on the default values for the
name and the bus_info. If the driver provides values, do nothing.

When doing memory registration, the PF may respond with
GDMA_STATUS_MORE_ENTRIES to indicate a follow request is needed. This is
not an error and should be processed as expected.

The number of maximum SGl entries should be computed from the maximum
WQE size for the intended queue type and the corresponding OOB data
size. This guarantees the hardware queue can successfully queue requests
up to the queue depth exposed to the upper layer.

For outgoing packets, the PF requires the VF to configure the vport with
corresponding protection domain and doorbell ID for the kernel or user
context. The vport can't be shared between different contexts.

Implement the logic to exclusively take over the vport by either the
Ethernet device or RDMA device.

Clean up pcs-xpcs accessors

This series cleans up the pcs-xpcs code to use mdiodev accessors for
read/write just like xpcs_modify_changed() does. In order to do this,
we need to introduce the mdiodev clause 45 accessors.
