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....

Thanks to report from Neil Hoggarth I found a missing UNLOCK in2008-05-21T21:06:17ZJack F Vogeljfv@FreeBSD.org2008-05-21T21:06:17Zurn:sha1:458575f87d68f0e57ed33654d3676bcae546260f
the watchdog code. This delta also incorporates some missing PCI
IDs that got added.
PR 122928 - might be fixed by this, no verification at this point.

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 em2008-04-02T22:00:36ZJack F Vogeljfv@FreeBSD.org2008-04-02T22:00:36Zurn:sha1:e9d8b9c383a9cbaf984df56650d52fb85c76f57b
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.

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 :)
