How to get network card/hardware level timestamps with websocketpp

[rshankk]

We would like to read the timestamp at which the packet was received on the network card/kernel to measure the kernel queue delay. In normal sockets, we can receive it using Linux socket options

https://www.kernel.org/doc/Documentation/networking/timestamping.txt

Is it exposed via websocketpp? How do we enable it or retrieve network card level timestamps?
