我想知道最近收到的路由器广告的m标志和o标志的值.从内核源代码我知道存储了m标志和o标志.
- /*
- * 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);
- .

解决方法
