RDS: TCP: Add sysctl tunables for sndbuf/rcvbuf on rds-tcp socket
Add per-net sysctl tunables to set the size of sndbuf and
rcvbuf on the kernel tcp socket.
The tunables are added at /proc/sys/net/rds/tcp/rds_tcp_sndbuf
and /proc/sys/net/rds/tcp/rds_tcp_rcvbuf.
These values must be set before accept() or connect(),
and there may be an arbitrary number of existing rds-tcp
sockets when the tunable is modified. To make sure that all
connections in the netns pick up the same value for the tunable,
we reset existing rds-tcp connections in the netns, so that
they can reconnect with the new parameters.
