Detailed Description

template<typename Key, typename Value>
class gs::RegionFIFOCache< Key, Value >

RegionFIFOCache - A simple FIFO cache for region-based address lookups.

This cache uses First-In-First-Out (FIFO) eviction policy, removing the oldest entry by insertion time (not by access pattern). Each entry covers an entire memory region, allowing range-based lookups.

Note: This is NOT an LRU cache - frequently accessed regions may still be evicted if they were added early. For true LRU behavior, use RegionLRUCache instead.

Each router instance has its own cache (instance-level storage).
