Defaults are calculated at boot time from amount of available
memory.
+tcp_min_rtt_wlen - INTEGER
+ The window length of the windowed min filter to track the minimum RTT.
+ A shorter window lets a flow more quickly pick up new (higher)
+ minimum RTT when it is moved to a longer path (e.g., due to traffic
+ engineering). A longer window makes the filter more resistant to RTT
+ inflations such as transient congestion. The unit is seconds.
+ Default: 300
+
tcp_moderate_rcvbuf - BOOLEAN
If set, TCP performs receive buffer auto-tuning, attempting to
automatically size the buffer (no greater than tcp_rmem[2]) to
you should think about lowering this value, such sockets
may consume significant resources. Cf. tcp_max_orphans.
+tcp_recovery - INTEGER
+ This value is a bitmap to enable various experimental loss recovery
+ features.
+
+ RACK: 0x1 enables the RACK loss detection for fast detection of lost
+ retransmissions and tail drops.
+
+ Default: 0x1
+
tcp_reordering - INTEGER
Initial reordering level of packets in a TCP stream.
TCP stack can then dynamically adjust flow reordering level
