其中m标志和o标志将存储在Linux中

问题描述

我想知道最近收到的路由器广告的m标志和o标志的值.从内核源代码中，我知道存储了m标志和o标志.

I want to know the value of m flag and o flag of recently received Router Advertisement. From the kernel source code I came to know that m flag and o flag are stored.

  /*
   * Remember the managed/otherconf flags from most recently
   * received RA message (RFC 2462) -- yoshfuji
  */
  in6_dev->if_flags = (in6_dev->if_flags & ~(IF_RA_MANAGED |
                          IF_RA_OTHERCONF)) |
                          (ra_msg->icmph.icmp6_addrconf_managed ?
                                   IF_RA_MANAGED : 0) |
                           (ra_msg->icmph.icmp6_addrconf_other ?
                                   IF_RA_OTHERCONF : 0);
  .
  .
  .

然后，我相信必须可以使用ioctl或proc文件系统或任何其他方法来检索这些值.任何人都可以指出这一点.

Then I believe it must be possible to retrieve those values using ioctl or proc filesystem or any other method. Could anyone please point that way.
