call flop/fold turn. weak or standard?

[gregorio]

villain 21/15/9 over 60 hands, but AF is not reliable
Flop AF=oo, but only based on 12 flops: 4 bets, 4 folds, 4 checks; River AF=oo based on 2 rivers.

In limit I raise flop and prolly calldown to 3-bet. Here I don't know that the donk means; could be air on paired board or could be trips wanting to play big pot.

I call flop and see what he does on turn, and there's no way I can call that size bet. It looks like he is trying to get it all in by river. Is calling flop okay? Any point in r/f the flop or is that just spew here?
