After OS requests to down a link on a physical network port, the
traffic is no longer being processed but the physical link with
a link partner is still established.

Currently there is a feature (Link down on close) which allows
to physically bring the link down (after OS request).

With this patch new feature with similar capability is introduced:
TOTAL_PORT_SHUTDOWN
Allows to physically disable the link on the NIC's port.
If enabled, (after link down request from the OS)
no link, traffic or led activity is possible on that port.

If I40E_FLAG_TOTAL_PORT_SHUTDOWN is enabled, the
I40E_FLAG_LINK_DOWN_ON_CLOSE_ENABLED must be explicitly forced to
true and cannot be disabled at that time.
The functionalities are exclusive in terms of configuration, but
they also have similar behavior (allowing to disable physical link
of the port), with following differences:
- LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time
  and is supported by whole family of 7xx Intel Ethernet Controllers
- TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS)
  only if motherboard's BIOS and NIC's FW has support of it
- when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought
  down by sending phy_type=0 to NIC's FW
- when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead
  the link is being brought down by clearing bit
  (I40E_AQ_PHY_ENABLE_LINK) in abilities field of
  i40e_aq_set_phy_config structure

Introduced changes:
- new private flag I40E_FLAG_TOTAL_PORT_SHUTDOWN for handling the
  feature
- probe of NVM if the feature was enabled at driver's port
  initialization
- special handling on link-down procedure to let FW physically
  shutdown the port if the feature was enabled

As with other networking drivers, remove the unnecessary driver version
from the Intel drivers. The ethtool driver information and module version
will then report the kernel version instead.

For ixgbe, i40e and ice drivers, the driver passes the driver version to
the firmware to confirm that we are up and running.  So we now pass the
value of UTS_RELEASE to the firmware.  This adminq call is required per
the HAS document.  The Device then sends an indication to the BMC that the
PF driver is present. This is done using Host NC Driver Status Indication
in NC-SI Get Link command or via the Host Network Controller Driver Status
Change AEN.

What the BMC may do with this information is implementation-dependent, but
this is a standard NC-SI 1.1 command we honor per the HAS.

When the AF_XDP buffer allocator was introduced, the Rx SW ring
"rx_bi" allocation was moved from i40e_setup_rx_descriptors()
function, and was instead done in the i40e_configure_rx_ring()
function.

This broke the ethtool set_ringparam() hook for changing the Rx
descriptor count, which was relying on i40e_setup_rx_descriptors() to
handle the allocation.

Fix this by adding an explicit i40e_alloc_rx_bi() call to

Changing descriptor count via 'ethtool -G' is not persistent across resets.
When PF reset occurs, we roll back to the default value of vsi->num_desc,
which is used then in i40e_alloc_rings to set descriptor count. XDP does a
PF reset so when user has changed the descriptor count and load XDP
program, the default count will be back there.

To fix this:
  * introduce new VSI members - num_tx_desc and num_rx_desc in favour of
    num_desc
  * set them in i40e_set_ringparam to user's values
  * set them to default values in i40e_set_num_rings_in_vsi only when they
