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.

Update every header file and other locations to consistently use
Intel(R) instead of just Intel. Also update copyright year of files
which we modified.

The 1588 support within fm10k does not work correctly with the current
version of the switch management software, and likely never worked
correctly to begin with. Remove support for PTP/1588. Update copyright
year for all these files while we're touching them.

Rather than wrapping fm10k_dcbnl.c and fm10k_debugfs.c support with
#ifdef blocks, just conditionally include the .o files in the Makefile.
Also, since we're modifying it, update the copyright year on the
Makefile.

This change adds support for the Linux PTP Hardware clock and timestamping
functionality provided by the hardware. There are actually two cases that
this timestamping is meant to support.
The first case would be an ordinary clock scenario. In this configuration
the host interface does not have access to BAR 4. However all of the host
interfaces should be locked into the same boundary clock region and as such
they are all on the same clock anyway. With this being the case they can
synchronize among themselves and only need to adjust the offset since they
are all on the same clock with the same frequency.
The second case is a boundary clock scenario. This is a special case and
would require both BAR 4 access, and a means of presenting a netdev per
boundary region. The current plan is to use DSA at some point in the
future to provide these interfaces, but the DSA portion is still under
development.

This patch adds limited debugfs support for the driver. Most of the
functionality needed for dumping registers is already provided via ethtool.
The only thing we saw that we really neeed was the ability to dump the
descriptor rings so as such this patch will add a fm10k directory containing a
listing of directories each one with a unique PCI Bus, Device, and Function
number. Each of those BDF directories will have a list of q_vectors, and
the q_vectors will contain a file for each of the Rx/Tx rings that are a part
of the vector. For example:
# ls -RD /sys/kernel/debug/fm10k/
/sys/kernel/debug/fm10k/:
0000:01:00.0
/sys/kernel/debug/fm10k/0000:01:00.0:

This patch adds support for management of the limited QOS features of the
FM10000 interface. Specifically we can support up to 8 traffic classes,
however the part only provides 1 Rx and 1 Tx FIFO in the host interface and
as a result this can lead to head-of-line blocking on Rx. This can be
avoided by setting PFC only for priorities that cannot afford to drop
frames.

This patch adds support for the mailbox that connects the PF to the Switch
Management entity. This mailbox will pass TLV formatted messages between
the two entities by using a pair of shared ring buffers.
The primary use of the mailbox is to configure L2 forwarding addresses,
VLANs, and general resource allocation from the switch.
