+stale_loss_cnt - INTEGER
+ The number of MPTCP-level retransmission intervals with no traffic and
+ pending outstanding data on a given subflow required to declare it stale.
+ The packet scheduler ignores stale subflows.
+ A low stale_loss_cnt value allows for fast active-backup switch-over,
+ an high value maximize links utilization on edge scenarios e.g. lossy
+ link with high BER or peer pausing the data processing.
+
+ This is a per-namespace sysctl.
