Wang Chen dad9b335c6 netdevice: Fix promiscuity and allmulti overflow ... Max of promiscuity and allmulti plus positive @inc can cause overflow. Fox example: when allmulti=0xFFFFFFFF, any caller give dev_set_allmulti() a positive @inc will cause allmulti be off. This is not what we want, though it's rare case. The fix is that only negative @inc will cause allmulti or promiscuity be off and when any caller makes the counters touch the roof, we return error. Change of v2: Change void function dev_set_promiscuity/allmulti to return int. So callers can get the overflow error. Caller's fix will be done later. Change of v3: 1. Since we return error to caller, we don't need to print KERN_ERROR, KERN_WARNING is enough. 2. In dev_set_promiscuity(), if __dev_set_promiscuity() failed, we return at once.
