tcp: Add SNMP counters for backlog and min_ttl drops
Commit 6b03a53a (tcp: use limited socket backlog) added the possibility of dropping frames when backlog queue is full. Commit d218d111 (tcp: Generalized TTL Security Mechanism) added the possibility of dropping frames when TTL is under a given limit. This patch adds new SNMP MIB entries, named TCPBacklogDrop and TCPMinTTLDrop, published in /proc/net/netstat in TcpExt: line netstat -s | egrep "TCPBacklogDrop|TCPMinTTLDrop" TCPBacklogDrop: 0 TCPMinTTLDrop: 0 Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.
