The device IDs for the Ethernet SDI Adapter devices were never added to
the upstream driver. The IDs are already in the pci.ids database, and
are supported by the out-of-tree driver.
Add the device IDs now, so that the upstream driver can recognize and
load these devices.

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.

If the fm10k interface is brought up, but the switch manager software is
not running, the driver will continuously request the lport map every
few seconds in the base driver watchdog routine. Eventually after
several minutes the switch mailbox Tx fifo will fill up and the mailbox
will timeout, resulting in a reset. This reset will appear as if for no
reason, and occurs regularly every few minutes until the switch manager
software is loaded.
Prevent this from happening by only requesting the lport map after we've
verified the switch mailbox is tx_ready. In order to simplify code logic
and reduce code duplication, implement this as a new function pointer
"mac.ops.request_lport_map" which the VF will not implement. Otherwise,
we have to duplicate the tx_ready check outside of
fm10k_get_host_state_generic, or re-implement most of
fm10k_get_host_state_generic in the pf version.
The resulting code is simpler and easier to understand, and prevents the
PF from continuously requesting lport map and filling the Tx fifo of
a switch mailbox that isn't ready.

Don't report FM10K_ERR_REQUESTS_PENDING when we fail to disable queues
within the timeout. This can occur due to a hardware Tx hang, or when
the switch ethernet fabric is resetting while we are transmitting
traffic. It can sometimes take up to 500ms before the Tx DMA engine
gives up. Instead, just skip the DMA engine check and perform
a data-path reset anyways. Add a statistic counter to keep track of the
number of resets occurring while we have pending DMA on the rings.
In order to prevent having to re-assign err to 0, re-order the
last few items of the reset_hw_pf function so that we don't perform
"return err" at the end.

Use a new #define FM10K_VLAN_OVERRIDE even though we're using the exact
same bit. The reason for this is clarity in the code, otherwise you can
read FM10K_VLAN_CLEAR and think it should be removed. Also add a comment
explaining why the FM10K_VLAN_OVERRIDE bit is set.

The 1588 support within fm10k does not work correctly with the current

The Intel Ethernet Switch FM10000 Host Interface interrupt throttle
timers are based on the PCIe link speed. Because of this, the value
being programmed into the ITR registers must be scaled accordingly.
For the PF, this is as simple as reading the PCIe link speed and storing
the result. However, in the case of SR-IOV, the VF's interrupt throttle
timers are based on the link speed of the PF. However, the VF is unable
to get the link speed information from its configuration space, so the
PF must inform it of what scale to use.
Rather than pass this scale via mailbox message, take advantage of
unused bits in the TDLEN register to pass the scale. It is the
responsibility of the PF to program this for the VF while setting up the
VF queues and the responsibility of the VF to get the information
accordingly. This is preferable because it allows the VF to set up the
interrupts properly during initialization and matches how the MAC
address is passed in the TDBAL/TDBAH registers.
Since we're modifying fm10k_type.h, we may as well also update the
copyright year.

It is possible that the PF has not yet assigned resources to the VF.
Although rare, this could result in the VF attempting to read queues it
does not own and result in FUM or THI faults in the PF. To prevent this,
check queue 0 before we continue in init_hw_vf.

Add a private ethtool flag to enable display of these statistics, which
are generally less useful. However, sometimes it can be useful for
debugging purposes. The most useful portion is the ability to see what
the PF thinks the VF mailboxes look like.

The FM10000 host interface can only support up to 184 bytes when
performing tunnel offloads. Because of this, a check was added to
prevent the driver from attempting to feed a header to the hardware too
big for it to parse. Make this check a little more robust by calculating
the inner L4 header length based on whether it is TCP or UDP.

This change adds the messaging support needed to support PTP. In the case
of Tx timestamps it is necessary for the Switch Management entity to return
the frames via the mailbox as the host interface cannot know which port the
timestamp will be delivered to. In addition there is only one clock on the
entire switch, as such the entity that has BAR 4 access is the only one who
can actually update the frequency as it is the only one with access.
