使用 boost 发送 icmp 数据包会清除校验和字节

Question

使用 Boost Asio 发送 ICMPv6 回显请求时，每当我执行 send_to 或 async_send_to 调用时，某些层似乎正在清除校验和。使用命令行 ping 实用程序时，没有问题。对于任何调用，当我查看 Wireshark 中的传出数据包时，所有字段：类型、代码、标识符、序列和有效负载都会被表示。加上正确的字节在调用前后的缓冲区中。看看这里的图片：

Wireshark capture icmpv6

这是要重现的代码。这是 Boost 1.62，VS2015。

#include <boost\asio.hpp>
#include <boost\thread.hpp>

using boost::asio::ip::address_v6;
using boost::asio::ip::icmp;

const char* ICMPREQUESTBODY_ = "abcdefghijklmnopqrstuvwabcdefghi";
const unsigned short ICMPIDENTIFIER_ = 1;
unsigned short tempchecksum = 0x5d46;
unsigned int icmpsequence_ = 70;
unsigned char ICMPv6TYPEECHOREQUEST_ = 128;
unsigned char ICMPv6CODE_ = 0;

int main()
{
    boost::asio::io_service io;
    boost::asio::io_service::work iowrk(io);
    boost::thread iothread(boost::bind(&boost::asio::io_service::run, &io));

    auto source = address_v6::from_string("2601:XXX:XXX:XXX::106");
    auto destination = address_v6::from_string("2601:XXX:XXX:XXX::202");
    icmp::endpoint remote_endpoint = boost::asio::ip::icmp::endpoint(destination, 0);
    icmp::endpoint local_endpoint(icmp::v6(), 0);

    icmp::socket elsocko(io, local_endpoint);

    unsigned char icmppacket[40];
    icmppacket[0] = ICMPv6TYPEECHOREQUEST_;
    icmppacket[1] = ICMPv6CODE_;
    icmppacket[2] = (tempchecksum & 0xff00) >> 8;
    icmppacket[3] = (tempchecksum & 0x00ff);
    icmppacket[4] = (ICMPIDENTIFIER_ & 0xff00) >> 8;
    icmppacket[5] = (ICMPIDENTIFIER_ & 0x00ff);
    icmppacket[6] = (icmpsequence_ & 0xff00) >> 8;
    icmppacket[7] = (icmpsequence_ & 0x00ff);
    memcpy(&icmppacket[8], ICMPREQUESTBODY_, 32);

    elsocko.send_to(boost::asio::buffer(icmppacket), remote_endpoint);

    //boost::asio::streambuf reply_buffer_;
    //elsocko.receive_from(reply_buffer_.prepare(65535), remote_endpoint);
}

目的地没有响应，因为校验和无效。是什么原因造成的/我该如何解决？

禁用 McAfee LiveSafe 防火墙允许 icmpv6 ping 正常工作。似乎没有直接解决此问题的设置。
