- This version has support for the new Intel Avoton systems,
including 2.5Gb support, further it now has IPv6/TSO6 support as
well. Shared code has been updated where necessary as well. Thanks
to my new assistant Eric Joyner for doing the transmit path changes
to bring in the IPv6/TSO6 support. Thanks to Gleb for catching the
one bug and change needed in NETMAP.

- bear with me, there are lots of white space changes, I would not
do them, but I am a mere consumer of this stuff and if these drivers
are to stay in shape they need to be taken.
em driver changes: support for the new i217/i218 interfaces
igb driver changes:
- TX mq start has a quick turnaround to the stack
- Link/media handling improvement
- When link status changes happen the current flow control state
will now be displayed.
- A few white space/style changes.
lem driver changes:
- the shared code uncovered a bogus write to the RLPML register
(which does not exist in this hardware) in the vlan code,this
is removed.
order to avoid otherwise harmless witness warnings when these are acquired
at the same time and due to both using MTX_NETWORK_LOCK as their type.
The right fix actually would be to use different, descriptive types for
these. However, the latter would require undesirable changes to the shared
code base. Another approach would be to just supply NULL as the type, which
was deemed as less desirable though as it would cause the unique but cryptic
name also to be used for the type and to diverge from the type used by other
network device drivers.

- Two struct members eee_disable are used in a function that expects
an int *, so declare them int, not bool.
- igb_tx_ctx_setup() returns a boolean value, so declare it bool, not int.
- igb_header_split is passed to TUNABLE_INT, so delcare it int, not bool.
- igb_tso_setup() returns a bool, so declare it bool, not boolean_t.
- Do not re-define bool/true/false if the symbols already exist.

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.
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
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
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....
