+# Makefile — Compila o programa eBPF sockmap
+#
+# Comandos:
+#   make            → Compila tudo
+#   make vmlinux    → Gera vmlinux.h do kernel atual
+#   make bpf        → Compila o programa BPF
+#   make clean      → Limpa arquivos compilados
+#   make docker-up  → Sobe os containers Docker
+#   make docker-down→ Para os containers
+#   make load       → Carrega o eBPF sockmap
+#   make unload     → Remove o eBPF sockmap
+#   make status     → Mostra status do sockmap
+#   make benchmark  → Roda benchmark de latência
