with the current initial RTO of 1second. With this the final timeout
for an active TCP connection attempt will happen after 127seconds.
-tcp_timestamps - BOOLEAN
- Enable timestamps as defined in RFC1323.
+tcp_timestamps - INTEGER
+Enable timestamps as defined in RFC1323.
+ 0: Disabled.
+ 1: Enable timestamps as defined in RFC1323 and use random offset for
+ each connection rather than only using the current time.
+ 2: Like 1, but without random offsets.
+ Default: 1
tcp_min_tso_segs - INTEGER
Minimal number of segments per TSO frame.
By default this is turned off.
+enhanced_dad - BOOLEAN
+ Include a nonce option in the IPv6 neighbor solicitation messages used for
+ duplicate address detection per RFC7527. A received DAD NS will only signal
+ a duplicate address if the nonce is different. This avoids any false
+ detection of duplicates due to loopback of the NS messages that we send.
+ The nonce option will be sent on an interface unless both of
+ conf/{all,interface}/enhanced_dad are set to FALSE.
+ Default: TRUE
+
icmp/*:
ratelimit - INTEGER
Limit the maximal rates for sending ICMPv6 packets.
