ip6 regressions end of November 2025

[vrpolakatcisco]

While results with AVF driver are also affected by #4109, looking at trending [0] this might be two different regressions, 2n-zn2 being affected few days sooner than others. 2n-grc is not affected by this (only by #4110), so this might be something Intel-specific.

Deeper investigation is needed.
