For software that interfaces with Bitcoin Core via RPC, it can be useful to know whether the fRelayTxes flag is set. It could be added to `getnetworkinfo`.

CNode* pnode = new CNode(hSocket, addrConnect, pszDest ? pszDest : "", false);
        pnode->AddRef();
        {
            LOCK(cs_vNodes);
            vNodes.push_back(pnode);
        }
        pnode->nTimeConnected = GetTime();
        return pnode;
    } else if (!proxyConnectionFailed) {
        
        
        addrman.Attempt(addrConnect);
    }
    return NULL;
}
void CNode::CloseSocketDisconnect()
{
    fDisconnect = true;
    if (hSocket != INVALID_SOCKET)
    {
        LogPrint("net", "disconnecting peer=%d\n", id);
        CloseSocket(hSocket);
    }
    
    TRY_LOCK(cs_vRecvMsg, lockRecv);
    if (lockRecv)
        vRecvMsg.clear();
}
