- Proposed replacement for SIOC{ADD,DEL}MULTI and

- It is more expensive, but I believe,
- it is really correct solution: reentereble, safe and fault tolerant.
-
- IFF_PROMISC/IFF_ALLMULTI/SIOC{ADD/DEL}MULTI are faked by keeping
- reference count and global flag, so that real status is
- (gflag|(count != 0)), so that we can use obsolete faulty interface
- not harming clever users.
