Improve reliability of the mailbox communication and remove
its potential flaws that may lead to the undefined or faulty behavior.
Recently some users reported issues on ESX with 10G Intel NICs which were
found to be caused by incorrect implementation of the PF-VF mailbox
communication.
Technical investigation highlighted areas to improve in the communication
between PF or VF that wants to send the message (sender) and the other
part which receives the message (receiver):
- Locking the mailbox when the sender wants to send a message
- Releasing the mailbox when the communication ends
- Returning the result of the mailbox message execution

Add new handling for error codes:
IXGBE_ERR_CONFIG - ixgbe_mbx_operations is not correctly set
IXGBE_ERR_TIMEOUT - mailbox operation, e.g. poll for message, timeout

After many years of having a ~30 line copyright and license header to our
source files, we are finally able to reduce that to one line with the
advent of the SPDX identifier.
Also caught a few files missing the SPDX license identifier, so fixed
them up.

Fix the code comments to align with drivers/net/ code commenting style,
as well as whitespace issues. The whitespace issues resolve checkpatch
errors, like lines exceeding 80 chars (except for strings) and the use
of tabs where possible.

This patch adds initial support for VFs on a new mac - X550.
The patch adds the basic structures and device IDs for the X550 VFs

This change merges the ixgbevf_tx_map call and the ixgbevf_tx_queue call
into a single function. In order to make room for this setting of cmd_type
and olinfo flags is done in separate functions.

This patch creates new functions for ring initialization,
ixgbevf_configure_tx_ring() and ixgbevf_configure_rx_ring(). The work done
in these function previously was spread between several other functions and
this change should hopefully lead to greater readability and make the code
more like ixgbe. This patch also moves the placement of some older functions
to avoid having to write prototypes. It also promotes a couple of debug
messages to errors.

This change adds support for DCB and SR-IOV from the VF. With this change
in place the VF will correctly use a traffic class other than 0 in the case
that the PF is configured with the default user priority belonging to a
traffic class other than 0.

This change makes it so that the VF can support the PF/VF API negotiation
protocol. Specifically in this case we are adding support for API 1.0
which will mean that the VF is capable of cleaning up buffers that span
multiple descriptors without triggering an error.

The interrupt registers accessed in ixgbevf are more similar to the igb
style registers than they are to the ixgbe style registers. As such we
would be better off setting up the code for the EICS, EIMS, EICS, EIAM, and
EIAC like we do in igb instead of ixgbe.
