Added gremlin option to client, controllable via
ClientAPI::Config::gremlinConfig string.
The gremlin option allows extra packet latency
or unreliability to be added to the tunnel.
The format of the option is a comma-separated list
of numerical parameters:
send_delay_ms, recv_delay_ms, send_drop_prob, recv_drop_prob
Parameter description:
send_delay_ms : delay packets by n milliseconds before
transmission (UDP/TCP).
recv_delay_ms : delay received packets by n milliseconds

Added gremlin option to client, controllable via
ClientAPI::Config::gremlinConfig string.
The gremlin option allows extra packet latency
or unreliability to be added to the tunnel.
The format of the option is a comma-separated list
of numerical parameters:
send_delay_ms, recv_delay_ms, send_drop_prob, recv_drop_prob
Parameter description:
send_delay_ms : delay packets by n milliseconds before
transmission (UDP/TCP).
recv_delay_ms : delay received packets by n milliseconds
before processing them (UDP/TCP).
send_drop_prob : drop sent packets with probability 1/n
(UDP only).
recv_drop_prob : drop received packets with probability
1/n (UDP only).
Set any parameter to 0 to disable.
Gremlin parameters currently work with UDP and TCP
transport as documented above, but not for proxy transport.
Client must be built with the OPENVPN_GREMLIN flag to compile
gremlin functionality.
Command-line client can set the gremlin config
string using --gremlin or -G, for example:
--gremlin=250,250,64,64
When using the above parameters, an extra 500 milliseconds
will be added to round-trip latency, and 1/64 sent or
received packets will be dropped.
