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.

Now that we have a working MAC/VLAN queue for handling MAC/VLAN messages
from the netdev, replace the default handler for the VF<->PF messages.
This new handler is very similar to the default code, but uses the
MAC/VLAN queue instead of sending the message directly. Unfortunately we
can't easily re-use the default code, so we'll just replace the entire
function.
This ensures that a VF requesting a large number of VLANs or MAC
addresses does not start a reset cycle, as explained in the commit which
introduced the message queue.

Currently, any error responses from the switch manager after an
LPORT_MAP request are silently ignored. At most the mailbox message will
be reported as an error. This can result in unexpected behavior when the
switch manager has configured a port with zero bandwidth. Add support
for reading the fm10k_swapi_error structure from LPORT_MAP responses.
If the message contains the necessary TLV and has a non-zero error code,
report link down, clear the dglort_map, and delay the next
get_host_state call by a reasonable delay. Also log an error message
indicating that the LPORT_MAP request failed.
The delay ensures preventing an interrupt storm on the switch manager,
and reduces the number of mailbox messages we send in this scenario
drastically.

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.

The TLV format for little endian structures is actually 4 byte aligned
copy. To this end, we need to add an additional __aligned(4) marker
along with __packed to ensure that these structures are actually 4 byte
aligned and packed correctly. Use of just __packed will not work as this
will result in 1byte alignment which is incorrect. Add a comment
explaining the reasoning behind why these structures need the special
treatment.

Make functions that should be static. While we're at it, fix the function

This patch adds the __attribute__((packed)) indicator to some structures
which are overlayed onto a TLV message. These structures must be packed
as small as possible in order to correctly align when copied into the
mailbox buffer. Without doing so, the receiving mailbox code incorrectly
parses the values and we get invalid message responses from the switch
manager software.
