Update the Intel igb driver to version 2.4.0 - 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.

Refresh on the shared code for the E1000 drivers. - 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.

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 :)

Update code from Intel: - Sync shared code with Intel internal - New client chipset support added - em driver - fixes to 82574, limit queues to 1 but use MSIX - em driver - large changes in TX checksum offload and tso code, thanks to yongari. - some small changes for watchdog issues. - igb driver - local timer watchdog code was missing locking this and a couple other watchdog related fixes. - bug in rx discard found by Andrew Boyer, check for null pointer

Update to igb and em:
em revision 7.0.0: - Using driver devclass, seperate legacy (pre-pcie) code into a seperate source file. This will at least help protect against regression issues. It compiles along with em, and is transparent to end use, devices in each appear to be 'emX'. When using em in a modular form this also allows the legacy stuff to be defined out. - Add tx and rx rings as in igb, in the 82574 this becomes actual multiqueue for the first time (2 queues) while in other PCIE adapters its just make code cleaner. - Add RX mbuf handling logic that matches igb, this will eliminate packet drops due to temporary mbuf shortage.
igb revision 1.9.3: - Following the ixgbe code, use a new approach in what was called 'get_buf', the routine now has been made independent of rxeof, it now does the update to the engine TDT register, this design allows temporary mbuf resources to become non-critical, not requiring a packet to be discarded, instead it just returns and does not increment the tail pointer. - With the above change it was also unnecessary to keep 'spare' maps around, since we do not have the discard issue. - Performance tweaks and improvements to the code also.

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

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.

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....

This delta has a few important items:
PR 122839 is fixed in both em and in igb
Second, the issue on building modules since the static kernel build changes is now resolved. I was not able to get the fancier directory hierarchy working, but this works, both em and igb build as modules now.
Third, there is now support in em for two new NICs, Hartwell (or 82574) is a low cost PCIE dual port adapter that has MSIX, for this release it uses 3 vectors only, RX, TX, and LINK. In the next release I will add a second TX and RX queue. Also, there is support here for ICH10, the followon to ICH9. Both of these are early releases, general availability will follow soon.
Fourth: On Hartwell and ICH10 we now have IEEE 1588 PTP support, I have implemented this in a provisional way so that early adopters may try and comment on the functionality. The IOCTL structure may change. This feature is off by default, you need to edit the Makefile and add the EM_TIMESYNC define to get the code.
Enjoy all!!

This update primarily addresses the ability to have both the em and the igb driver static in the kernel. But it also reflects some other bug fixes in my development stream at Intel. PR 122373 is also fixed in this code.

This change introduces a split to the Intel E1000 driver, now rather than just em, there is an igb driver (this follows behavior with our Linux drivers). All adapters up to the 82575 are supported in em, and new client/desktop support will continue to be in that adapter.
The igb driver is for new server NICs like the 82575 and its followons. Advanced features for virtualization and performance will be in this driver.
Also, both drivers now have shared code that is up to the latest we have released. Some stylistic changes as well.
Enjoy :)

Driver version 6.7.3 - Bring HEAD up to the latest shared code - Fix TSO problem using limited MSS and forwarding - Dual lock implementation - New device support - For my ease, this code can compile in either 6.x or later - brings this driver in sync with the 6.3

This delta adds two bug fixes: one that makes HW Offload logic in legacy codepath match the 82575, without this we were seeing bridging fail on 82546 adapters. Secondly, I have limited TSO to PCI Express adapters, I meant to do this and it got dropped in the earlier delta. Next, I am dropping in the latest shared code from our development team, consensus was that this should be done frequently, so I am :)

$FreeBSD$ tags are not compilable C code; wrap in either __FBSDID() or in comments for .c and .h files respectively. Jack may want to clean up style or other aspects once he's up and about again, but this gets the kernel compiling.

Merge in the new driver (6.5.0) of Intel. This has a new shared code infrastructure that is family specific and modular. There is also support for our latest gigabit nic, the 82575 that is MSI/X and multiqueue capable.
The new shared code changes some interfaces to the core code but testing at Intel has been going on for months, it is fairly stable.
I have attempted to be careful in retaining any fixes that CURRENT had and we did not, I apologize in advance if any thing gets clobbered, I'm sure I'll hear about it :)
