The documentation for SIOCGIFFLAGS/SIOCSIFFLAGS in netdevice.7 lists
IFF_LOWER_UP, IFF_DORMANT and IFF_ECHO, but those can't be set in
ifr_flags as it is only a short and the flags start at 1<<16.

I don't know what's the history of that.

Judging from commit message in the commit linked above it was added by
mistake. As noted the flags are accessible via netlink, just not via
SIOCGIFFLAGS.

I should have CCd netdev@ before.  Thanks for the update.  Let's see if
anyone there can comment.

Thanks,

Alex
