Hi all,
Any idea for what do we need gflags of net_device?
I believe gflags stand for global flags (though the header file, netdevice.h,
does not say so explicitly).


I see that they are initialized only in
__dev_change_flags() ,
 in net/core/dev.c, in

But it is not clear what is their meaning.

Any ideas? can someone elaborate on this ?

rgs,
Andy
