Merge branch 'tcp-allow-to-reduce-max-rto'
Eric Dumazet says:
====================
tcp: allow to reduce max RTO
This is a followup of a discussion started 6 months ago
by Jason Xing.
Some applications want to lower the time between each
retransmit attempts.
TCP_KEEPINTVL and TCP_KEEPCNT socket options don't
work around the issue.
This series adds:
- a new TCP level socket option (TCP_RTO_MAX_MS)
- a new sysctl (/proc/sys/net/ipv4/tcp_rto_max_ms)
Admins and/or applications can now change the max rto value
at their own risk.
