Reduce TCP latency when using socketcand

[faisal-shah]

Is your feature request related to a problem? Please describe.

The TCP socket is not configured to optimize for latency. Given that, communicating over protocols with tight(er) timing requirements can fail when using socketcand to bridge CAN networks over a TCP connection.

Describe the solution you'd like

The TCP socket should be configured with TCP_NODELAY, and TCP_QUICKACK (where available) to reduce latency.
