ixv(4): Allow PF to control the VF link state

This patch adds checks of a VF link state provided by PF via mailbox
API. Such change enables the PF to disable a VF administratively.

Since command needed by the PF to control the VF is introduced in
mailbox api version 1.2, this patch also bumps supported mailbox api
version to 1.2.

ixgbe: cleanup spelling mistakes in comments

Several functions in the driver code have a weird function comment
formatting which uses two spaces instead of only one space for the main
function body.

This formatting will be mechanically fixed by sed in a future patch, but
doing so leads to some spelling warnings on that patch. Cleanup the
spelling mistakes that will be detected first. This way, it is easier to
verify the mechanical transformation done by sed in the following patch.

ixgbe: remove whitespace in function comments

Remove unnecessary extra whitespace on all function comments, replacing
' * ' with ' * '.

This was done automatically via sed using the following transformation:

sys/dev: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

because the receive ring tail pointer was being fixed up as a side
effect of other activity).

NOTE: This is a technology preview, while it has undergone development
tests, Intel has not yet completed full validation of the feature.
It is being integrated for early access and customer testing.

Add support for certain Intel X550 devices.

These include standalone X550 adapters, X552 10GbE backplane, and
X552/X557-AT 10GBASE-T; with the latter two being integrated into Xeon D SoCs.

As well, this bumps the ixgbe version number to 2.8.3, and includes updates
to shared code for support for the new devices.

Update to the Intel ixgbe driver:
- Split the driver into independent pf and vf loadables. This is
in preparation for SRIOV support which will be following shortly.
This also allows us to keep a seperate revision control over the
two parts, making for easier sustaining.
- Make the TX/RX code a shared/seperated file, in the old code base
the ixv code would miss fixes that went into ixgbe, this model
will eliminate that problem.
- The driver loadables will now match the device names, something that
has been requested for some time.
- Rather than a modules/ixgbe there is now modules/ix and modules/ixv
- It will also be possible to make your static kernel with only one
or the other for streamlined installs, or both.

Enjoy!

Add quad port probe support, this gives the admin proper information about the slot
(which should be a PCIE Gen 3 slot for this adapter) by looking back thru the PCI
parent devices to the slot device.

The fix above also corrects the bandwidth display to GT/s rather than the
incorrect Gb/s

Next, allow the use of ALTQ if you select the compile option IXGBE_LEGACY_TX.

Allow the use of 'unsupported' optic modules by a compile option as well.

Add a phy reset capability into the stop code, this is so a static configured
driver will still behave properly when taken down (not being able to unload it).

This revision synchronizes the shared code with Intel internal current code,
and note that it now includes DCB supporting code, this was necessitated by
some internal changes with the code, but it also will provide the opportunity
to develop this feature in the core driver down the road.

I have edited the README to get rid of some of the worse anachronisms in it
as well, its by no means as robust as I might wish at this point however.

Oh, I also have included some conditional stuff in the code so it will be
compatible in both the 9.X and 10 environments.

Performance has been a focus in recent changes and I believe this revision
driver will perform very well in most workloads.

First, sync to internal shared code, and then

Fixes:
- flow control - don't override user value on re-init
- fix to make 1G optics work correctly
- change to interrupt enabling - some bits were incorrect
for certain hardware.
- certain stats fixes, remove a duplicate increment of
ierror, thanks to Scott Long for pointing these out.
- shared code link interface changed, requiring some
core code changes to accomodate this.
- add an m_adj() to ETHER_ALIGN on the recieve side, this
was requested by Mike Karels, thanks Mike.
- Multicast code corrections also thanks to Mike Karels.

Update to the ixgbe driver:
- Add a couple of new devices
- Flow control changes in shared and core code
- Bug fix to Flow Director for 82598
- Shared code sync to internal with required core change

Thanks to those helping in the testing and improvements to this driver!

New hardware support: Intel X540 adapter support added.
Some shared code reorganization along with the new adapter.
Sync changes to OACTIVE in igb into this driver.
Misc small fixes.

Update ixgbe driver to verion 2.3.6
- This adds a VM SRIOV interface, ixv, it is however
transparent to the user, it links with the ixgbe.ko,
but when ixgbe is loaded in a virtualized guest with
SRIOV configured this will be detected.
- Sync shared code to latest
- Many bug fixes and improvements, thanks to everyone
who has been using the driver and reporting issues.
