AWS elasticloadbalancing documentation change
Summary
Updated terminology from 'ELB' to 'Elastic Load Balancing' and added clarification about ICMP requirements for Path MTU Discovery
Security assessment
The change replaces acronyms with full product names and maintains existing security guidance about ICMP fragmentation messages. No new security content is added, and there's no evidence of addressing a specific vulnerability.
