igb: Add support of SerDes Forced mode for certain hardware

[dann frazier]

Please cherry-pick 2c670b5 from upstream for oneiric. It closes a race that can cause link negotation to fail.

[Impact]
Severity: high; network does not obtain link
Frequency: rare

[Development Fix]
commit 2c670b5

[Stable Fix]
Trivial cherry-pick from upstream

[Test Case]
Not easily reproducible

[Regression Potential]
Minimal; code is very isolated, stable upstream, and we've been using it in an OEM project for several months w/ no problems.

@Dann

For this request, can you create a SRU bug (just adding some text to this one would work). Then make a request on the kernel team mailing list:

<email address hidden>

I've added the necessary content to the Description field, but I do
not have access to the "Nominate for series" feature described on:
  https://wiki.ubuntu.com/StableReleaseUpdates?action=show&redirect=SRU

Can you help me out there?

I'll wait until the SRU tag is added to do this unless told otherwise.

Hi Dann -- You should be all set here to send the cherry-pick request per Comment #4

[Herton R. Krzesinski (herton)]

This bug is awaiting verification that the kernel for Oneiric in -proposed solves the problem (3.0.0-15.24). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-oneiric' to 'verification-done-oneiric'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

My testing uncovered no regressions.
