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:

sed 's/^ \* / * /'

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.

ixgbe(4): Update HEAD (p3) to 3.2.12-k

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.

Resolve a few build issues, add module directories back into Makefile,
then correct a NETMAP problem resulting from the split, and finally
temporarily disable the X550 functionality.

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.

MFC after: 2 weeks

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!

MFC after:5 days

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.

A new jail(8) with a configuration file, to replace the work currently done
by /etc/rc.d/jail.

MFC of version 2.1.7 of the ixgbe driver.

Update the driver to Intel version 2.1.6
- add some new hardware support for 82599
- Big change to interrupt architecture, it now
uses a queue which contains an RX/TX pair as
the recipient of the interrupt. This will reduce
overall system interrupts/msix usage.
- Improved RX mbuf handling: the old get_buf routine
is no longer synchronized with rxeof, this allows
the elimination of packet discards due to mbuf
allocation failure.
- Much simplified and improved AIM code, it now
happens in the queue interrupt context and takes
into account both the traffic on the RX AND TX
side.
- variety of small tweaks, like ring size, that have
been seen as performance improvements.
- Thanks to those that provided feedback or suggested
changes, I hope I've caught all of them.

Update driver to Intel version 2.0.7:

This adds new feature support for the 82599, a hardware
assist to LRO, doing this required a large revamp to the
RX cleanup code because the descriptor ring may not be
processed out of order, this necessitated the elimination
of global pointers.

Additionally, the RX routine now does not refresh mbufs
on every descriptor, rather it will do a range, and then
update the hardware pointer at that time. These are
performance oriented changes.

The TX side now has a cleaner simpler watchdog algorithm
as well, in TX cleanup a read of ticks is stored, that
can then be compared in local_timer to determine if
there is a hang.

Various other cleanups along the way, thanks to all who
have provided input and testing.

Update for the Intel 10G driver, this adds support for
newest hardware, adds multiqueue tx interface, infrastructure
cleanup to allow up to 32 MSIX vectors on newer Nehalem systems.
Bug fixes, etc.

Update the ixgbe driver to 1.7.4, this includes support
for the new 82599 adapter family, adds header split, and
many small fixes. The driver should now be added to the
GENERIC kernel.

Updated ixgbe driver - version 1.6.2

-This version has header split, and as a result a number of
aspects of the code have been improved/simplified.
- Interrupt handling refined for performance
- Many small bugs fixed along the way

MFC after: ASAP - in time for 7.1

- Import the HEAD csup code which is the basis for the cvsmode work.

This updates the ixgbe driver to Intel internal version 1.4.7
Shared code changes, core driver fixes, vlan event/filter support

Also Kip Macy's fix to allow any number of queues, thanks Kip!

This is driver version 1.4.4 of the Intel ixgbe driver.
-It has new hardware support
-It uses a new method of TX cleanup called Head Write Back
-It includes the provisional generic TCP LRO feature contributed
by Myricom and made general purpose by me. This should move into
the stack upon approval but for this driver drop its in here.
-Also bug fixes and etc...

MFC in a week if no serious issues arise.

This is an update to the new Intel 10G 82598 driver.
The first drop was Beta, this code is expected to be the release version.
Note that this driver code will build in either 6.2 or 7. If you
use the code in 6.2 you will not get TSO or MSI/X support but it will
function in a legacy mode.
