Enable timestamps as defined in RFC1323.
+tcp_min_tso_segs - INTEGER
+ Minimal number of segments per TSO frame.
+ Since linux-3.12, TCP does an automatic sizing of TSO frames,
+ depending on flow rate, instead of filling 64Kbytes packets.
+ For specific usages, it's possible to force TCP to build big
+ TSO frames. Note that TCP stack might split too big TSO packets
+ if available window is too small.
+ Default: 2
tcp_tso_win_divisor - INTEGER
This allows control over what percentage of the congestion window
can be consumed by a single TSO frame.
