e1000: Revert Update intel shared code

This reverts commit fc7682b17f3738573099b8b03f5628dcc8148adb.

This will be done incrementally to help with bisecting an issue in
later I21x devices (ich8lan).

e1000: Update intel shared code

Sync the e1000 shared code with DPDK shared code
"cid-gigabit.2020.06.05.tar.gz released by ND"

Primary focus was on client platforms (ich8lan). More work remains here
but we need an Intel contact for client networking.

net: prefer ETHER_ADDR_LEN over ETH_ADDR_LEN

A couple of drivers and one place in if.c use ETH_ADDR_LEN, even though
net/ethernet.h provides an equivalent ETHER_ADDR_LEN definition.

Cleanup all of the locations which refer to ETH_ADDR_LEN to use the
standard ETHER_ADDR_LEN instead.

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.

Update em(4) to 7.6.1; update igb(4) to 2.5.3.

Major changes:

- Add i219/i219(2) hardware support. (Found on Skylake generation and newer
chipsets.)
- Further to the last Skylake support diff, this one also includes support for
the Lewisburg chipset (i219(3)).

- Add a workaround to an igb hardware errata.
All 1G server products need to have IPv6 extension header parsing turned off.
This should be listed in the specification updates for current 1G server
products, e.g. for i350 it's errata #37 in this document:
http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/ethernet-controller-i350-spec-update.pdf

- Avoton (i354) PHY errata workaround added

And a bunch of minor fixes, as well as #defines for things that the current
em(4)/igb(4) drivers don't implement.

Revert 287914,287762.

Reports of breakage on igb(4) have been narrowed down to 287762 and 287914
is an dependant change.

Submitted by: erj

Update em(4) with D3162 after testing further on hardware that failed
to attach with the last version of this commit. This commit fixes
attach failures on "ICH8" class devices via modifications to
e1000_init_nvm_params_ich8lan()

- Fix compiler warning in 80003es2lan.c
- Add return value handler for e1000_*_kmrn_reg_80003es2lan
- Fix usage of DEBUGOUT
- Remove unnecessary variable initializations.
- Removed unused variables (complaints from gcc).
- Edit defines in 82571.h.
- Add workaround for igb hw errata.
- Shared code changes for Skylake/I219 support.
- Remove unused OBFF and LTR functions.

Tested by some of the folks that reported breakage in previous incarnation.

Sync with Intel internal source:
shared code update and small changes in core required
Add support for new i210/i211 devices
Improve queue calculation based on mac type

MFC after:5 days

Part 1 of two parts, this is the shared code changes in
support of new deltas for both em and igb drivers.

Note that I am not able to track all the bugs fixed in
this code, I am a consumer of it as a component of my
core drivers. It is important to keep the FreeBSD drivers
up to date with it however.

One important note is there is a key fix for 82574 in this
update. Also, there are lots of white space changes, I am
not happy about them but have no control over it :)

Fix the shared code to be consistent with Intel-internal,
and now build.

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

MFC of the em/igb drivers

Update the 1G drivers, shared code sync with Intel,
igb now has a queue notion that has a single interrupt
with an RX/TX pair, this will reduce the total interrupts
seen on a system. Both em and igb have a new watchdog
method. igb has fixes from Pyun Yong-Hyeon that have
improved stability, thank you :)

I wish to MFC this for 7.3 asap, please test if able.

Resync with Intel versions of both the em and igb
drivers. These add new hardware support, most importantly
the pch (i5 chipset) in the em driver. Also, both drivers
now have the simplified (and I hope improved) watchdog
code. The igb driver uses the new RX cleanup that I
first implemented in ixgbe.

em - version 6.9.24
igb - version 1.8.4

Updates for both the em and igb drivers, add support
for multiqueue tx, shared code updates, new device
support, and some bug fixes.

This delta syncs the em and igb drivers with Intel,
adds header split and SCTP support into the igb driver.
Various small improvements and fixes.

MFC after: 2 weeks

This delta is primarily a fix for es2lan devices that
will sometimes fail to initialize problem due to a lock
contention with management hardware. However, in order to
deliver that fix it was necessary to take a shared code
update as a whole, and this required scattered changes in
the core code to be compatible.

The em driver now has VLAN HW support added as the igb
driver had previously.

MFC after: ASAP - in time for 7.1 RELEASE

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

Merge of the source for igb and em into dev/e1000, this
proved to be necessary to make the static drivers work
in EITHER/OR or BOTH configurations. Modules will still
build in sys/modules/igb or em as before.

This also updates the igb driver for support for the 82576
adapter, adds shared code fixes, and etc....

MFC after: ASAP
