	However, I did find another bug I introduced during the "mii
refactor" patch that you mentioned as being the original source of the
problem.  That bug will cause 802.3ad to not notice speed changes.

	Could you test the patch below on your 2.6.68.7 and/or 2.6.27.19
and see if it resolves your problem (without the forcedeth patch)?

There was something missing from the header to make it compile.. I found 
that in a later version. Patch below fixed the problem (without the 
forcedeth patch).
