Jiri-
I do not want to hold up the entire series, especially since three of
the four patches are not against our drivers, but I would like to have
these changes tested in our validation labs.

I will apply the series internally for testing.  In the meantime, if I
get an ACK from Carolyn Wyborny and Greg Rose on the igb/igbvf patch, I
am good with Dave applying the series.
