Relating to or characteristic of a donation or gift; pertaining to the act of giving.
From Medieval Latin donalis, derived from donare (to give). It's an older adjective form that fell out of common usage as 'donatory' and 'donative' became preferred.
This is a beautifully archaic word—'donal' sounds poetic but it lost out to its cousins 'donative' and 'donatory' in the competitive world of English adjectives!
