"struct ice_aqc_sw_rules_elem" has multiple other structs has unions, based on which one is used allocated memory being less than the size of "struct ice_aqc_sw_rules_elem" is logically correct but compiler is complaining about it. As a solution making sure allocated memory size is at least size of "struct ice_aqc_sw_rules_elem". The function to use the struct is 'ice_aq_sw_rules()', and it already has parameter for size of the rule, allocating more than needed shouldn't cause any problem.
