TCP 송수신 hot MIB와 초기 counter
1-50이 문서는 `netns_ipv4`에서 사용하는 Linux MIB enum counter의 fast-path update 위치를 나열합니다. Counter type은 `unsigned_long`이고 name은 `/proc/net/netstat` 계열 통계와 연결되는 kernel symbol입니다.
TX write-hot counter에는 keepalive, delayed ACK, autocorking, zero-window advertisement와 original data sent가 있습니다. RX write-hot counter에는 header prediction hit, receive coalescing, pure ACK, high-performance ACK와 delivered data가 표시됩니다. 그 밖의 Syncookie, prune, overflow, memory과 lock drop counter도 원문 enum 순서를 유지합니다.
