Is Frenzy a "mind-affecting effect"?

[Tyger]

Short story long, our Frenzied Berserker has a magic item that grants "+10 to save against all mind-affecting effects, all poisons and diseases, all stunning attacks, paralysis, sleep, and death effects."

Would that apply to the save to break out of a Frenzy or to avoid going into Frenzy?

RAW, no. Frenzy isn't mentioned as being mind-affecting, so it isn't.
