SipHash was specifically designed to be resistant to hash flooding attacks.
FWIW, the SMHasher test suite takes the view [1] that defense against hash flooding attacks is a concern for the hash table's collision resolution method, which is a fair point. Nonetheless, SipHash was subsequently adopted by several programming languages' standard libraries for use in hash tables. SipHash is also notable for its clear and concise specification, including security claims, preliminary cryptanalysis, and a discussion on hash flooding [2].
