How to stop receiving?

[keeword]

NewRawSocketRelayWithRelayConn create a goroutine to receive packets, but do not provide method to stop it.
If I call RawSocketRelay.Stop, then I got panic:

unexpected fault address 0x7f2771980008
fatal error: fault

So, how to stop receiving?

NewRawSocketRelayWithRelayConn was supposed to be an internal function, use NewRawSocketRelay or NewRawSocketRelayPcap instead, I have changed it to internal in v0.8.0.
