Commentary by Sāyaṇa: Ṛgveda-bhāṣya

Draviṇodas is an appellative of Agni; donor (das) of wealth, or of strength, draviṇa; adhvara is said to be the primary or essential ceremony, prakṛti-rūpa, e.g. agniṣṭoma; yajña related to mofied ceremonies, vikṛti-rupeṣu, e.g. ukthya, elsewhere refered to as offering with Soma: somasaṃsthayāgam
