MFC of igb fixes?

[Charles Owens]

Hello Jack,

I'm wondering if you have any thoughts with regard to the expected
timeframe for MFC of commit *203049*
<http://svn.freebsd.org/viewvc/base?view=revision&revision=203049> to
RELENG_8?   With igb NICS we're seeing flakiness with link-state
handling... and I'm worried that we could fall victim to problems others
have seen when putting the NIC under load.

Would you happen to have a version of the patch that is ready for
RELENG_8?  (we'd actually be applying it against RELENG_8_0, as that's
what we're currently bundling with our product).   I do note that you
made a few other minor fixes in the week or so following -- should these
be in the picture as well?

Any help or advise is appreciated.

The system in question is based on the Intel S5520UR motherboard... the
NICs are on-board (_not_ PCI-card-based).  During boot, the NICs are
detected as shown below.  At boot the NICs will always show link-state
as being active, whether or not a cable is plugged in.
